1.2.3 Printer Structure

The printer can be described as the complex of the following parts.In the next figure it is possible to see the internal printer architecture and where themajor blocks described below are located.

### MECHANICAL ASSY### PRINT HEAD### CABINET### ELECTRONIC HARDWARE### INKED RIBBON

Fig. 1.3 Printer Internal Architecture


GENICOM 3460 / 3480 / 3480+ 1.8 GEK-89537

1.2.3.1 Mechanical Assy

This block is composed of a rubber platen roller with a carriage carrying a print headwith 9 needles (3460 model) or 24 needles (3480/3480+ models) in front of theplaten.This movement is obtained via a step-motor (providing 1/120" movement per step)and a minipitch belt.

The movement of the rubber drum for paper traslation is obtained via a specific stepmotor providing a minimum movement of 1/144" for 9 needle model or 1/180" for 24needles model and a couple of minipitch belts.

The motion of the ribbon cartridge is obtained through a specific step-motorindipendently from the actual carriage speed, movement, direction and width.In this way in front of the print head there is a continuously renewing well inkedribbon. The ribbon speed is optimized to reduce conflicts with ribbon and graphicprintout appearance when ribbon and print head are moving in the same direction.

The color ribbon and the extended life black cartridges are moved up and downthrough a linear actuator (step motor) with a plastic coupler that transmits the axialmovement to the plastic print head mask installed on the color ribbon cartridge.

Another step motors is used for the A.G.A. (automatic gap adjustment) of the printhead movement to have the best perfomance on the paper in use.The printer is able to increase/decrease the strength of the needle stroke via MENU(selectable by User) to allow a high impact force also for multi-part forms (up to 7copies).

1.2.3.1.1 Tractor Unit Assy

A removable push-pull tractor unit is installed on the printer.Inside of it, a DC motor switches to engage/disengage the gear to allow the fanfoldor the single sheet to be fed.The tractor unit can be installed in two different positions depending on the type offanfold management (front - rear - both).In the next chapter all the paper handling possibilities of this mechanism aredetailed.

1.2.3.2 Print Head

The core of the printer is the print head, which is for both models an electromagneticnon- ballistic type with a life of 400 MChrs.There are three different print heads: 9 needles for 3460.

24 needles for 3480.24 needles for 3480+.

1.2.3.3 Cabinet

The cabinet allows safety-proof lifting of frontal part for ribbon substitution and paperpath check.It is composed of various parts to allow an easy access to all the printer internalparts.


GENICOM 3460 / 3480 / 3480+ 1.9 GEK-89537

1.2.3.4 Electronic Hardware

This section is composed of the following boards:

MAIN BOARD located in the bottom right side of the printer which controls themotors movement, the various input sensors, the parallel interface and the print headneedles.It also provides the management of the asynchronous host serial interface, externalsynchronous serial interface for mechanical options and fonts cartridge.

POWER SUPPLY BOARD located in the bottom left side of the printer whichprovides specific voltages for logical area, printhead needles and drive motors.There are two power supply boards: 120 and 220/240 Vac respectively.

OPERATOR PANEL BOARD placed on the front side of the printer driving 9 pushbuttons and 8 leds (3 for printer status and 5 for paper path selection).This board also drives a 16 Digit LCD Alphanumeric display to easily interact withparameters setting for menu operation.

SERIAL INTERFACE board located on the rear right side and plugged to the mainboard which drives the proper drivers for serial interface.

1.2.3.5 Inked Ribbon Cartridge

The ribbon cartridge is installed in different ways according to the ribbon types.In case of the black ribbon, the cartridge is fixed on both sides on four points.Its position is obliquous to the print line to automatically show the complete height ofthe ribbon in front of print head while printing on the full print line.

The inked ribbon inside of these cartridges is a continuous loop.

In case a color ribbon or an extended life black ribbon installed, the cartridge is fixedon both sides only on the two rear points, so that is is free to move its frontal partupward and downward.Its installation is parallel to the print line to assure the correct color band selection.A specific step motor is used to move the ribbon band up and down for colorselection.

1.2.3.6 Mechanical Options

This printer can provide some mechanical options :

AUTOMATIC SHEET FEEDER (up to 3 bins).Each bin has a DC motor inside it to automatically load the single sheet paper.Internally on the bin a series of gears takes the movement of the motor to the rubberroller shaft.Together with the first bin a PAPER STACKER is provided to collect the outputprinted paper.Also this part has an internal step motor to select the path where the paper shouldbe output.

Paper Handling Overview


GENICOM 3460 / 3480 / 3480+ 2.2 GEK-89537

2.1 Introduction

These printers are designed to be extremely flexible in paper handling.

Moreover, the mechanism has been designed to be, first of all, ergonomic for a betterand easier end-user operation.

2.1.1 Paper Handling Architecture

All the paper paths described below can co-exist and can be selectable via MENUand SW commands.

The printer automatically switches from one path to the other except for the rear pulltractor positions.

Via operator panel menu it is possible to select one format per each path (up to 6) ora single format (equal for all paths).

The basic configuration provides these ways to manage the paper formats:(In the next figure the paths for continuous modules are indicated as <#########>,while the paths for single sheet forms are indicated as --->; each path is identifiedwith a number).

### SINGLE SHEET

A semi-automatic frontal single sheet insertion (PATH 1).

The single sheet forms are manually loaded in this path.When a sheet is inserted, the sensors detect its presence and the printer loads the paper automatically without any other action.

### CONTINUOUS MODULE (FANFOLD)

Through a user installable/removable tractor unit the fanfold module can be fed through the following positions:

FRONT PUSH mode (PATH 2) with tractor group in position A, also overlapped with single sheet (PATH 1).

REAR PUSH mode (PATH 3) with tractor group in position B, also overlapped with single sheet (PATH 1).

REAR PULL mode with frontal insertion (PATH 4) with tractor group in position C, also overlapped with single sheet (PATH 1), exclusive with fanfold

in PATH 3.

REAR PULL mode (PATH 4) with tractor group in position C, with input from the bottom (PATH 5), also overlapped with single sheet (PATH 1) exclusive with fanfold in PATH 3.

For the first two paths, the continuous module exits from PATH 10.


GENICOM 3460 / 3480 / 3480+ 2.3 GEK-89537

### DOUBLE FANFOLDS

Through the optional second user installable/removable tractor unit the following feeding positions for continuous module are available :

DUAL PUSH fanfolds mode.The first fanfold from the front in push mode with basic tractor group in position A (PATH 2), the second from the rear in push mode with optional tractor group in position B (PATH 3), both overlapped with a single sheet (PATH 1).

For this path, the fanfolds exit (once at a time) from PATH 10.

PUSH&PULL fanfolds mode in which the fanfold can be fed from the front in push mode with the basic tractor group in position A (PATH 2) and at the same time is pulled from the second tractor group in position C (PATH 4).Also this configuration can be overlapped with a single sheet (PATH 1).

### AUTOMATIC SHEET FEEDER (ASF)

Through the optional Automatic Sheet Feeder the following feeding positions for single sheets are available :

REAR in the first bin (PATH 6). REAR in the second bin (PATH 7). REAR in the third bin (PATH 8).

Inside the paper output stacker, a mechanical switch allows the alternance between the output single sheets, which are collected to the output stacker (PATH 9), and the fanfold using this exit (PATH 10).

On the next figure 2.1 it is possible to see the internal architecture of this printer inwhich the different paper paths handled by the new design of the mechanicalassembly are put in evidence.

On the table 2.1 it is possible to find the Paper Path Types that can be selectedaccording to the printer Path Configurations.

2.1.2 Paper Feeder Movements

The next figures 2.2, 2.3 show how the feeder movements are done in this printer.

RIGHT SIDE

On the right side of the printer, the paper motor (1) drives a series of gears and feederassy through the main paper belt (5) .Directly connected through the paper motor gear, there is an idle gear (2) which givesthe motion to the front push-pull tractor assy idle gear (4).The tractor gear (3) is engaged-disengaged on the tractor idle gear (4) through alinear movement done by the push-pull tractor assy motor.

The main paper motor belt also drives the platen assy pulley gear (9) and the lowerfeeder assy gear (7).A movable idle (5) is present to give the proper belt tension.

A second belt called platen belt (10), takes the motion from the platen assy internalgear and drives the upper feeder assy gear (11).

The support spring rollers (8) and the pinch rollers of the bail assy (12) assure the correctpaper feeding from the manual front path and the out of platen area respectively. Seechapter 2.2 for the manual actions for opening the pinch rollers.

LEFT SIDE

On the left side the upper feeder assy gear (11) gives the motion to the rear push-pulltractor assy through a couple of gears and to the paper stacker gear (15).A manual lever engages the tractor idle gear (4) in two possible modes:

- through the movable gear (14A) for the rear push path action.- through the idle gear (13) the movable gear (14B) for the rear pull action.

Chapter 2.2 shows the rear tractor push-pull lever action.

The tractor gear (3) is engaged-disengaged on the tractor idle gear (4) through a linearmovement done by the push-pull tractor assy motor.

A specific motorized roller (18) is present on each ASF to feed the paper sheet up tothe friction rollers (17).

On this side there is also the mechanism which automatically opens and closes thefriction rollers located below the platen assy (17) when the rear push path is choosen.This action is done through a combined movement of the carriage motor and the papermotor.

When the friction rollers must be moved, according with the selected paper path, thecarriage motor moves the carriage unit to the left-most position, causing the movementof the friction lever assy and the engagement of the open gear (9) to the sector gear(16).At this point, a paper movement slides the the friction bar assy with the sector gearsplined to its shaft (16) to the proper open or closed position.

• Carriage assy (1)• Friction Lever assy (2)• Friction Bar assy (3) with Sector gear (4)• Open Gear (5)• Friction Rollers (6)

At manufacturing site, the mechanical assy is mounted and the tests and diagnosticare done to store the proper rear fanfold sensor values in the NVM according to theproper friction rollers position (the rear fanfold sensor tuning values stored in NVM aredifferent if the friction rollers are opened or closed).

It is important not to move the carriage and paper advance knob manually to changethe friction bar position because this would cause the loss of the correspondancebetween mechanism position and the sensor tuning .

If any intervention of this kind has been done, it is indispensable to run the T&D toassure the correct correspondance.

IMPORTANT REMARK

### For the REAR PUSH mode, the fanfold must have a maximum thickness of 0.35 mm instead of 0.635 mm of the other paths.

### For the REAR PULL mode, a manual intervention is necessary.The bail assy must be lifted (upper position) and the selection slider located on the left side of the printer must be in its up position to assure the correct rotation of

the rear tractor (see chapter 2.2.5 or user manual for major details).

5.1.3 Print Head Gap

This adjustment is required only if one of these parts are removed:- Platen Assy- Carriage Assy- Rear Bar.

Two little white spots are painted on the left-side metal platen axe and on the springsupport assy. These spots are the locations for the manufacturing adjustment andindicate the maximum platen eccentricity and the platen/carriage eccentricity points(i.e.: the minimum print head gap is with carriage assy located over the spring supportwhite spot and with the platen rotation for the white spot aligned with the print head).Their position and meaning are indicated as follow and they can use as a referencepoints in the procedure after described when these parts are not replaced.

1) Support spring assy.A white dot is painted on the support spring assy.It indicates (joint to the white dots reported in item 2a) the position in

the carriage assy axial movement in which there is the maximium drumeccentricity.

2) Platen assy.2a) Two white dots are painted on the left metal axe of the platen assy and

its relative bearing.Matchingof these dots (joint to the white dot reported in item 1)

indicates the position for the platen assy rotation in which there is themaximum drum eccentricity.

i.e.: the minimum distance from the print head needles to the platen iswith the combination of item 1) and 2a).

2b) A red dot is painted on the left metal axe of the platen.The matching of this dot with the white dot on the bearing indicates the

position for the platen assy rotation in which there is themaximum drum

eccentricityin the area where the AGA routine is running during T&D.

3) Rear bar.Two white dots are painted on the eccentric bushing and on the right

side located in the right ide of the rear bar.They ndicate the position of the eccentric bushing to obtain the

minimum value for the platen drum and peint head alignment parallelism.

Procedure

For the complete print head gap adjustment procedure follow all the steps (1 to 12).For the simplified procedure follow all the the steps without 7b, 7c,7d and 7e.

- If only the carriage assy has been replaced with a new one, it is possible readjust the print head gap with the reduced procedure by the helping of the painted dots of the current parts.

- If only the support spring assy has been replaced with a new one, beforeinstall it paint a white dot in the same location of the replaced one andreadjust the print head gap with the reduced procedure by the helping

ofthe painted dots .

- If only the platen assy has been replaced with a new one, it is possible


GENICOM 3460 / 3480 / 3480+ 5.7 GEK-89537

readjust the print head gap following the complete procedure.- If only the rear bar has been removed, it is possible readjust the print head

gap with the reduced procedure by the helping of the painted dots ofthe current parts for new ptinters (with the eccentric bushinginstalled), otherwise the complete procedure must be done.

Standard Value : 0.25 mm to 0.30 mm (0.01 to 0.012 inch)Tools : Feeler Gauge

To assure the correct printhead gap for all the carriage movements, follow these steps:

1) Remove paper, the ribbon cartridge and the bail assy.

2) Moves the print head in its farmost position from the platen and then remove the AGA marker.

3) Moves the carriage assy until the print head nose is in front of the white dot painted on the support spring assy and, at the same time, rotates the platen assy

until the white dots on its left axe and bearing matching.

4) Insert a feeler gauge between the print head needles and the platen drum and assure for its ortogonally position.

Remark: the feeler gauge end does not enter more than 20mm (0.78inch) from the print head mask top edge to avoid an incorrectmeasure due to the spring support mylar presence.

5) Gently move the print head towards the platen utilizing the AGA gear until the feeler gauge is frictioned.

6) If the printers has not the reference colored points, verify with the feeler gauge that in any carriage position the distance between the print head and the platen is

between 0.25 - 0.3mm (item 2 of figure 5.3).

7) Furthermore, the platen ends must be aligned with the print head by 0.08mm (0.003 inch).

Example : ------------------------------------------------------- platen A B C

###### ###### ###### printhead needles

Possible Values: A B C --------------------------------- 0.25 0.25 0.25

0.3 0.3 0.30.22 0.27 0.3

0.3 0.27 0.22

In case the alignment is not correct (>0.08mm) follows these steps:

If the white dot is painted on the eccentric bushing:7a) Verify if the white dot on the rear bar eccentric bushing matches with the one located on the right side.


GENICOM 3460 / 3480 / 3480+ 5.8 GEK-89537

If they are not matching, unscrew the right side screw securing the smaller bar, gently rotate the eccentric bushing with a plier for its alignment with the

white dot. While holding the eccentric bushing, firmly tighten the right side screw.

7b) Tighten the left side rear bar screw.

7c) Loosen the right side rear bar screw (item 1).

7d) Gently rotate the eccentric bushing with a plier (item 2) and verify the alignment in its best condition.

7e) After the adjustment, while holding the eccentric bushing with the plier, firmly tighten the right side screw.

For older printer without eccentric bushing, the best parallelism can be obtined in asimilar procedure by the movement of the rear bar in the right side hole.

8) Mount the AGA marker by slightly tightening the right side screw indicated on figure5.4(item A). Set the AGA wheel on reference 1.

9) Hold the AGA wheel on reference 1 and slowly dropit to its normal position. If during the gears engagement, two teeth are touching, put the AGA marker gear

in the first free tooth and tighten both the screw (item A and B of figure 5.4). The AGA marker should be on reference 0.9.

Check for its complete and free rotation.

10) Put the AGA marker in the farmost position from the platen. Manually insert a 80 gr/m2 single sheet paper between the platen and the

print head. It must be free to slide up and down. Slowly move the AGA wheelinward.

The paper must lightly frictioned when the AGA reference is on 1.

11) Power on the printer and run the T&D 12 routine for AGA setting. Select the single sheet insertion. Load a 80gr/m2 single sheet paper. The AGA proceure must be run when the red dot painted on the left axe of

the platen matches with the white dot on the bearing. Use the paper advance knob to reach this point and run the T&D AGA

routine until the AGA marker is on reference 1-1.3. If the platen assy has not the red dot painted, the procedure must be

repeated at least three times on different point along the diameter of the platenand select the point in which the AGA marker has the minimum value andpaints the red dot on its left axe for future use.

12) Store the correct AGA value and power off the printer.

SS means single sheet (the LOAD/FF key must be pressed).FF means fanfold (the PAPER ⇓ key must be pressed).

If the fanfold paper is choosen, the printer automatically loads the paperengaged on the front tractor, otherwise the display will show "LOADPAPER" and the LOAD/FF key must be pressed.

If the single sheet is choosen, the display will show "INSERT CUT SHEET".If a sheet is put in this path, the printer automatically loads it.

After the paper loading, the display shows "+ AGA n -" and then "YES<- STORE ->NO".

YES means the store in NVM of the selected value (LOAD/FF key) and skip to next fixed gap procedure.

NO means that this test will be repeated (PAPER ⇓ key).

If the PAPER ⇓ key is pressed, the AGA calibration procedure is executedagain and the display shows "+ AGA n -".

+ means a positive change of the AGA value (LOAD/FF key)AGA means the execution of the AGA calibration test (LF key)n displays the AGA value.- means a negative change of the AGA value (PAPER ⇓ key)

The range of the variation is from -8 to +8 (every unit changes the gap of 0.03 mm).

5.1.8 Sensor Tuning

This adjustment is suggested when the main board is changed or if some problemsappear in the paper detection.

The paper sensors are reflecting type.They are driven by the main board in a dynamic mode.This means that the input led is driven by the + 5 Voltage with an impulse wave toincrease its life.The output signal enters in an analog multiplexer and then to the analog to digitalconverter port of the microprocessor (see figure 3.12).

The sensors are adjusted at manufacturing site with a proper T&D tool which storesthese output voltage levels of the three sensors detected with NO PAPER installed.This value is stored in NVM on main board.

If the main board or if some parameters of these sensors are changed (due to their life-parameters degradation or simply a different shining printer location), this level may notbe correct anymore for the normal operation of the printer.

Also if the mechanical assy has been disassembled in the friction bar assy part, checkthe coherence between the position of this part and the values stored in NVM (seechapter 6.4).

Check all these aspects and, enventually, readjust and memorize these values.


ALWAYS WITHOUT ANY PAPER INSERTED IN ALL PATHS.

Service Maintenance


GENICOM 3460 / 3480 / 3480+ 6.2 GEK-89537

6.1 Overview

This section describes how to maintain the printer in order to obtain from it always the bestperformances.

In this chapter it is possible to find also some helps to test printer and to identifydefective components using the Test & Diagnostic facilities.

For all other aspects regarding the printers setting and printer programming, please referto the following manuals:

• Model 3460/3480 User's manual (P.N. GEK-89170)• Model 3460 Programmer's manuals (P.N. GEK-89212)• Model 3480 Programmer's manuals (P.N. GEK-89213)

First-level maintenance is based on F.R.U. (field replaceable unit).

GENERAL REMARK

Pay attention to turn the printer off, unplug the power cord and wait for at least 5 minutesbefore starting with the cleaning operations due to the high temperature on somemechanical parts when the printer is on normal operation from a long time (print head,carriage motor, paper motor).Install the power supply cover tool if a printer maintenance is done when the printer ispowered on (see chapter 6.3.3).

6.2 Initial Ispection

When the printer presents a trouble, before proceeding to the service maintenance, aninitial inspection must be done.

In fact, a problem in the printout often is due to a bad or wrong condition of the printeritself.

The parameters that must be previous checked are: set-up, cleaning, paperspecification.After that, if the problem remains, a troubleshooting session can be activated.

6.2.1 Set-Up

Check for the following items to make sure they are fullfilled.

### Is the printer placed in a correct position ?### Is the environmental temperature in the nominal range ?### Is the relative humidity in the nominal range ?### Is the unit installed in a bad location ?

(Close to high temperatures or humidity, near heat sources, dusty areas,areas where gas is generated, exposed to direct sunlight)### Has the printer a good configuration ?


GENICOM 3460 / 3480 / 3480+ 6.3 GEK-89537

In the OPERATIONAL MENU under the PRINT STATUS item it is possible find threedifferent menu listings : SYSTEM, CONFIG and FORMAT.Please refer to the user manual for more details on all these items.

6.2.2 Cleaning

No preventive maintenance, on a schedule basis, is required.Periodic cleaning will help to keep your printer in top condition.

Clean the printer as follows:

### Use a neutral detergent or water solution on a soft cloth to clean dirt and greasefrom the cabinet of the printer.

### Do not use an abrasive cloth, alcohol, paint thinner or similar agents because thaymay cause discoloration and scratching.

### Do not LUBRICATE the main and rear shaft, but only clean dirt.

### Be especially carefull not do damage the electronic and mechanical components.

Check for the paper paths condition and to make sure they are correct.If they are dirty (by paper residues or by ink), please clean them using a soft cloth.

6.2.3 Paper Specifications

Also the paper is important to have high performances.

Check for the correct paper specifications.See chapter 1.3 and the USER manual for more details.

6.2.4 Consumables

Genicom reccomends to use only its original consumables with original packaging.In this way, a proper use of the printer at the quality level and reliability stated in the productcharacteristics can be assured.

All typical usage problems typically related to not certified consumables can be avoided,such as:an overall degradation of the printing quality level and often, the reduction of the total life ofthe product due to the fact that the proper working conditions of the print head and otherparts are not assured.

Moreover, the original consumables are controlled in compliance with the internationalstandard rules concering:

### no cancerous materials

### no inflammability of the plastic materials


GENICOM 3460 / 3480 / 3480+ 6.4 GEK-89537

### other standard


GENICOM 3460 / 3480 / 3480+ 6.5 GEK-89537

6.3 Troubleshooting Guide

The recommended sequences for the printer fault detection are:

### To observe initializing procedure and Operator Panel messages.

### To check power malfunctions.

### To run the SELF-TEST procedure.

### To run the T&D (Test and Diagnostic) procedure.

### If necessary, run the HEXADECIMAL dump procedure.

At any stage where appropriate, refer to the troubleshooting guide.

6.3.1 Initializing Phase

When the printer is powered on, before starting the normal operations, it performs aninitializing phase (BOOSTRAP).

During this phase the Software of the printer initializes the hardware resources of theprinter for the correct function.

### The display will show: STARTING UP

and then performs a full-matrix display check from leftmost to rightmost position.

### The display will show : ################################################

After a successfull initialization phase, the printer enters in the normal operation phase,moves the carriage assy on the left most position to check the home position sensorand goes in READY or WAIT state, depending on if the paper is already installed or not.

If the printer does not initialize correctly see next chapter to see the possible errormessages displayed on the LCD.

6.3.2 Printer Errors

Some errors can be displayed by the printer.These errors can be divided into three main groups:

### Status errors### Recoverable errors### Not recoverable errors

6.3.2.1 Status Errors


GENICOM 3460 / 3480 / 3480+ 6.6 GEK-89537

When an error of this kind occurs, the printer shows some messages to the User with theaction to do to fix or by-pass the error condition.See 3460 and 3480 Models User manuals for major details.

6.3.2.3 Unrecoverable Errors

When an error of this kind occurs, the printer is halted and enters in error state.

All these errors cannot be reset through specific actions and require the powering-off of theprinter.Typically all these problems appear if an internal error in the BOOSTRAP or NORMALoperation phases is detected.

If after powering-on the printer the problem appears again, run the T&D test as described inchapter 6.4 , to check the faulty O.R.U..If the message appears again, contact your nearest Technical Support.

In the BOOSTRAP phase the following messages can be displayed.If one of these messages appears, the BOOSTRAP phase is not positively ended and,consequently, the hardware resources of the printer are not initialized.

For all these messages, the fault mainly depends on the EPROMs or on themicrocontroller or on the data bus problems (Eproms or Main Board F.R.U.).

6.3.6 Fault Probability Guide

Please use this guide whenever a fault is detected but no special display configuration isdisplayed.

Usually, if a fault regards an electromechanical part and if no feed-back is arised, no error isdetected by the firmware of the printer.

In fact, except for the home postition and ribbon sensors, (that have a feed-back circuit toreturn the status condition), the other mechanical parts do not have a return feed-backbecause they are in open-loop circuit.

So, for example, if the paper does not advance, the fault regards these parts: (paper motor,driver circuit and logic H/W).For this fault, only the paper movement can be verified with a T&D printout.

6.4 Test & Diagnostic

6.4.1 Introduction

The TEST & DIAGNOSTIC program, abridged in "T&D", is adopted to check the variousfunctional parts composing the printer, and to diagnose possible operating defects whichmight occur during this phase.

The T&D program can also be considered as a software tool to support the productionactivities.It has been realized in order to avoid the shipment of printers not perfectly operating.

6.4.2 T&D Structure

The software architecture of this printer is composed of one layer called as "PLATFORM",which has the task to manage the interfaces towards the existing H/W resources, and an"APPLICATION" layer which contains modules for emulations management.

The T&D provision is an application module and uses the PLATFORM to accede the H/Wresources (engine, operator panel, nvm, etc.).

Under diagnostic conditions the whole RAM is checked to assure that there are no errors inthe area in which the Operating System will be allocated.

For this purpose, it has been stated that the portion of diagnostic procedure carrying outthese tests, should be executed at system's BOOTSTRAP.If, and only if bootstrap tests give positive result, the PLATFORM module and thediagnostic application will then be initialized.At this point, subsequent tests will be executed (NVM, plugs, printouts, etc...).

6.4.4 Execution of User T&D

The USER T&D is the T&D procedure for the field level maintenance.It requires the following:

### The T&D card plugged onto the right side slot provided in the cover.

### MFG jumper on operator panel board must be absent as default setting.

### The serial interface 232 and parallel interface loop-back connectors must be installed in the serial and in the parallel interface connectors.

### The mechanical options loop-back connector must be installed in the paper stacker connector.

### Insertion, before starting test, of some forms (136 characters, 72 lines) of fanfold module on the front tractor path.

### Press simultaneoulsy ON LINE and PAPER ⇓⇓ keys at power on for at least 2 seconds.

All tests indicated in the table 6.1 are one-shot or automatically sequential executeddepending by the first choice after the initialization phases (see chapter 6.4.6 ).

At the end, sample forms are printed out for all electromechanical checking and mechanicaladjustments.

During the execution of each test, the display will show some messages to show to thetechnician the activity in progress or the action the operator has to do in that moment.

NOTICE :

### It is indispensable that no paper modules are present in any paper paths when the T&Dprocedure is executed (the sensors must be not covered by the paper).

In fact, the T&D automatically adjusts, whitout any intervention, all the reflective sensors of the printer (single sheet, front fanfold, rear fanfold).

### The cover must be closed, otherwise a message "# COVER OPEN " will bedisplayed.

6.4.5 Loop-Back Connectors

The T&D can check also the functionalities of various I/F's existing on the printer.A proper loop-back connector must be used to have the correct feed-back.Three connectors are used for the following intefaces:

### Serial Interface loop-backs.They are composed by some wires that connect the output signals with the input signals of

these interfaces, one for the RS232 and the other for RS422 type.See figure 6.5A and 6.5B for diagrams.

### Parallel Interface loop-back.It is composed by some wires that connect the output signals with the input signals of this

interface plus an intergrated circuit (parallel latch) that provides the correct handling of thebidirectionality of the data input/output lines.

See figure 6.6 for diagram.

### Mechanical Options loop-back.This loop-back must be inserted in the connector located in the upper right side of the

mechanical assy in which the paper stacker assy must be inserted.It is composed by an integrated circuit (serial latch) that provides the correct handling of the

the data input/output lines.The insertion key of this loop-back provides the pin 1 at the top-right position (with the printer

in frontal view).See figure 6.7 for diagram.

NOTICE:

Insert the parallel interface and the mechanical options loop-backs only when the printer is poweredoff.

This test checks if the eproms present on the main board are of the proper type withrespect to the respective board (for 9 or 24 needles).

T&D 2 - CONTROLLER EPROM MEMORY TEST

This test executes the CRC with 31-degree polynomial, which involves the whole memoryaddressing (512 KB x 8 = 4 Mb).For a positive test issue, the computation must be 0.During the test the display shows "T&D 2 CRC ROM *".A flushing asterisk indicates the correct running of the test.

T&D 3 - FONT/EMULATION EPROM MEMORY TEST

This test executes the CRC with 31-degree polynomial, which involves the whole memoryaddressing (256 KB x 8 = 2 Mb).For a positive test issue, the computation must be 0.During the test the display shows "T&D 3 CRC CARD *".A flushing asterisk indicates the correct running of the test.

T&D 4 - GENERATOR EPROM MEMORY TEST

This test executes the CRC with 31-degree polynomial, which involves the whole memoryaddressing (512 KB x 8 = 4 Mb).For a positive test issue, the computation must be 0.During the test the display shows "T&D 3 CRC FONT *".A flushing asterisk indicates the correct running of the test.

T&D 5 - OPERATOR PANEL BOARD TEST

This test consists of a first reading, which checks for 9 keys to be opened.If one key is damaged (short circuit), an error message is displayed and the T&D is halted.After that, the test checks all the 8 leds of the printer.All these leds are lit and then off, then sequentially from right to left one led is lit for about0.5 second with an associated buzzer sound.


GENICOM 3460 / 3480 / 3480+ 6.41 GEK-89537

Then the test continues with a request to push sequentially the 9 keys from right to left.The display shows the message "PUSH KEY 1 --->" to indicate that the rightmost keyshould be pressed.Then, at every step the display shows the message "PUSH KEY (n)".If the wrong key is pressed, the buzzer sounds twice to advise the error.In case that the requested key is not activated within a few seconds, an error code isdisplayed.

T&D 6 - PARALLEL INTERFACE TEST

This test checks by means of loop-back plug closing, for the correct operation of control,status and data signals of the bi-directional interface (see loop-back diagram at chapter6.4.5).

T&D 8 - EEPROM MEMORY TEST (NVM)

This test controls the check-sum of the non-volatile memory (eeprom or nvm).

T&D 9 - SERIAL INTERFACE TEST

This test checks by means of loop-back plug closing, for the correct operation of control,status and data signals of the serial RS232 and RS422 interfaces (see loop-back diagramat chapter 6.4.5).

T&D 10 - MECHANICAL OPTIONS TEST

This test checks the mechanical option connector signals by means of a special loopback.For further details, refer to the Section dedicated to the diagrams of the loopback plugs inthis chapter.

T&D 11 - SENSOR TUNE RIBBON, COLOR MOTOR, RIBBON WELD and REAR FRICTION STATUS TESTs

SENSOR TUNEThis test is executed just before any mechanical movement (T&D 11 to T&D18 and eventuallyT&D20), so the T&D11 is the first impacted test.If one of these tests is skipped, the rear friction status check appear in the next one.This test is automatically done by the T&D program without any manual intervention.REMARK!Before running this test remove, if present, the paper from any paths.

FRICTION STATUSThis test is executed just before any mechanical movement (T&D 11 to T&D18 and eventuallyT&D20), so the T&D11 is the first impacted test.If one of these tests is skipped, the friction status check appear in the next one.

The last test is to verify and change, if necessary, the coherence between the internal NVMdata for the Friction Bar Position and the relative mechanical position of the bar itself.As described in chapter 2, in this printer there is an automatical movement of the friction

Interfaces


GENICOM 3460 / 3480 / 3480+ 8.2 GEK-89537

8.1 Overview

This chapter refers to the interfaces used on the printer.Information passing through the interface can be described in three separate aspects(levels):

1- Physical and electrical characteristics which enable the transferred signals to be recognized by both devices that are talking each other.

2- Link protocol signals and rules enabling and maintaining the connection and the transfer of data to be recognized and interpreted by both devices.

3- Device protocol the "language" which allows different products to give the same meaning to the transferred information.Refer to the USER MANUAL for all the recognized commands.

8.1.1 Hot Interfaces

All physically available interfaces are simultaneously connected to systems.When one is operating, the other interface(s) are busy unless the input memory reserved forthat interface has space enough to receive characters.To each interface an emulation is associated (by the operator) changing the interfaceparameters also the emulation environment.If there is not enough memory to store the complete environment, changing the interface incase of different emulations will reset the printer, including DLL data.The interface is reserved as soon as a first character is received, and until 10 sec. arepassed after the end of any printing activity without receiving any characters (any type,including service, commands etc).

8.2 IEEE 1284 Parallel Interface

The hardware of the parallel interface implemented in this printer is able to support the IEEE1284 interface, even if the actual level of FW is not able to manage it.This interface is a bi-directional extension of the existing personal computer parallelinterface (commonly known as the CENTRONICS interface).The bi-directional communication occurs using the signals of the currently interface.

This new interface has been issued due to the limitation of the actual standard parallelinterface with respect to the new PC environment.The serial port provides bi-directionality but does not offer enough bandwidth.The Standard parallel interface (Centronics) offers a higher but limited bandwidth and no bi-directionality.Centronics also requires a lot of assistance from the host CPU making it inadeguate forenvironments like Windows where multiple applications are running simultaneously.

FEATURES

1) This interface provides the capability to send data from the host to the peripheral deviceat higher speed than it was possible before.

This is accomplished by shortening the signal timing values where possible.2) This interface provides a path for data to be sent from the peripheral device to the

host using existing and future parallel port hardware.3) The reverse channel capability reduces the amount of user interaction needed to

operate the peripheral device.


GENICOM 3460 / 3480 / 3480+ 8.3 GEK-89537

For example, application program can ask a printer for a list of fonts currently available. The application can then decide if new fonts must be downloaded, rather than asking the user to do it.


GENICOM 3460 / 3480 / 3480+ 8.4 GEK-89537

8.2.1 Communication Modes

The IEEE1284 interface supports a number of distinct communication modes, and theinterpretation of interface signals depends on the current mode.

### Compatibility mode (Centronics)This is the lower level mode which provides an asynchronous, byte-wide forward (host-

to-peripheral) channel with data and status lines used according to their original definitions.In this mode, the host sends 8-bit bytes to the peripheral device over the interface data signal D1 ... D8.

### Nibble ModeThis mode provides an asynchronous, reverse (peripheral-to-host) channel, under control

of the host.In this mode, peripheral device to host data bytes are sent as two sequential, four-bit nibbles using the four peripheral-to-host status lines.This mode is used with Compatibility mode to implement a bi-directional channel.These two modes cannot be active simultaneously.

### Byte ModeThis is the higher mode supported by the printer. It provides an asynchronous, byte-wide reverse (peripheral-to-host) channel using the eight data lines of the interface for data and the control/status lines for handshaking.This mode is used with Compatibility mode to implement a bi-directional channel with transfer direction controlled by the host, when the host and the peripheral both support bi-directional use of the data lines.These two modes cannot be active simultaneously.

The highest interface mode can be selected via Menu: in this way the interface can belimited to: Centronics, Bidirectional Nibble, Bidirectional Byte.

8.2.2 Operating Phases

Interface operation is divided into different interface phases. Each communication modeconsists of one or more phases.Additional phases are defined toward initialization and transitions between communicationmodes.The names and interpretations of the interface signals may vary between phases, but areconsistent within each phase.

Compatibility Mode Phases

Compatibility Mode Forward Data Transfer phase.This phase begins when the host asserts nStrobe and ends following data hold time and nStrobe de-assertion (the host is not free to send the next data until the device acknowledges the transfer using nAck).The host may not initiate negotiation to a new operating mode until the interface returns to Compatibility Mode Forward Idle Phase.

Compatibility Mode Forward Idle PhaseThe interface is in Compatibility mode with no data transfer in progress.The host may initiate a data transfer in Compatibility mode, or may initiate negotiation to a new operating mode.


GENICOM 3460 / 3480 / 3480+ 8.5 GEK-89537


GENICOM 3460 / 3480 / 3480+ 8.6 GEK-89537

Nibble and Byte Mode Phases

Reverse Data Transfer phase.Data transfer from peripheral to host.

Reverse Host Busy Data Available phase.The peripheral has data to transmit.

Reverse Host Data Not Available phaseThe peripheral has no more data to trasmit.

Reverse Idle phaseNo data transfer in progress, the host is waiting for device data.When data is available, the peripheral will cause the interface to go to the Reverse Interrupt phase.

Reverse Interrupt phaseThis phase provides the mechanism for the peripheral to alert the host that it has data to transfer. While in this phase, the host may cause the interface to go to the Termination Phase.

Additional Phases

Initialization phaseThis phase includes both power-on initialization and host-driven interface reset.

Negotiation phaseSignal handshaking to change the signaling method from Compatibility Mode to Nibble or Byte.

Termination phaseA host-initiated transition phase in which the interface is changed from Nibble or Byte to Compatibility.

8.2.3 Negotiation

This interface is self adapting to the same mode as the system to which it is connected,also if it is not IEEE 1284 compliant.This means that a IEEE 1284 compliant host negotiates with the peripheral device todetermine whether or not the device is 1284 compliant by checking its status lines toinclude PError and nFault both at logic high levels for a particular host stimulus.(n Selectin set high in conjunction with host busy being set low to request a 1284 mode).Together with this stimulus, the IEEE 1284 interface protocol has been designed to allowthe host to request that the peripheral device uses various communication modes.This is accomplished by the host placing an extensibility request value on the data busduring the negotiation phase.

The value 00h means Nibble Mode, while the value 01h means Byte Mode

The printer answer on Xflag signal to this value.The Xflag affermative response is LOW for Nibble Mode, HIGH for Byte Mode.

8.2.4.1 Parallel Interface Signals Behaviour

HostClk / nWrite (nStrobe)Compatibility Mode: Set active low to transfer data into printer input latch.

Data is vaild while nStrobe is low.Negotiation phase: Set active low to transfer extensibility request value into printer input latch.

Data is valid on the falling edge of HostClk.Reverse Data Transfer phase: Set high during Nibble Mode transfer to avoid latching

data into printer.Pulsed low during Byte Mode transfers to acknowledge transfer of data from the printer.The printer shall ensure that this pulse does not transfer a new data into the printer input latch.

AD1..AD8 (Data 1...Data 8)Compatibility Mode: Forward channel DataNegotiation phase: Extensibility request value.Reverse Data Transfer phase: Nibble Mode: NOT USED

Byte Mode : Reverse channel Data

PrtClk (nAck)Compatibility Mode: Pulsed low by the printer to acknowledge the transfer of a

data from the host.Negotiation phase: Set low to acknowledge 1284 support, then set high to

indicate that the Xflag (Select) and data available flags may be read.

Reverse Data Transfer phase: Used in both Nibble and Byte Modes to qualify data being sent to the host.

Reverse Idle phase : Set low then high by printer to cause an interrupt indicating to host that data is available.

PrtBusy (Busy)Compatibility Mode: Driven high to indicate that the printer is not ready to

receive data.Negotiation phase: Reflects the present state of the printer's forward channel.Reverse Data Transfer phase: Nibble Mode: Data bits 3 then 7, then forward channel

busy status.Byte Mode : Forward channel busy status.

Reverse Idle phase : Forward channel busy status.

AckDataReq (PError)Compatibility Mode: Driven high to indicate that the printer has encountered an

error in the paper path.The printer shall set nFault low whenever it sets PError high.

Negotiation phase: Set high to indicate 1284 support, then follows nDataAvail (nFault).

Reverse Data Transfer phase: Nibble Mode: Data bits 2 then 6.Byte Mode : Same as nDataAvail (nFault)

Reverse Idle phase: Set high until host requests data transfer, then follows nDataAvail (nFault).


GENICOM 3460 / 3480 / 3480+ 8.10 GEK-89537

Xflag (Select)Compatibility Mode: Set high to indicate that the printer in on-line.Negotiation phase: The name Xflag refers to extensibility flag.

Used by the printer to reply to the requested extensibility byte sent by the host during the negotiation phase.The signal level is low for Nibble Mode, high for Byte Mode.

Reverse Data Transfer phase: Nibble Mode: Data bits 1 then 5.Byte Mode : Same as negotiation phase.

Reverse idle phase: Same as negotiation phase.

HostBusy (nAutofd)Compatibility Mode: Set low by host to put the printer into auto-line feed mode.Negotiation phase: Set low in conjunction with 1284 Active (NSelectIn) being

set high to request a 1284 mode.Then set high after printer sets PtrClk (nAck) low.

Reverse Data Transfer phase: Nibble Mode: Set low to indicate that host can receive printer-to-host data, then set high to acknowledge receipts of that nibble.

Byte Mode: Same as Nibble Mode to request and acknowledge bytes.Following a reverse channel transfer the

interface transitions to idle phase when HostBusy (nAutoFd) is set low and printer has no data available.

Reverse Idle phase: Set high in response to PtrClk (nAck) low pulse to re-enter reverse data transfer phase.Is set high with 1284 Active (nSelectIn) being set low, the 1284 idle phase is being aborted and the interface returns to Compatibility Mode.

Peripheral Logic High (+ 5V)Set high to indicate that all other signals sourced by the printer are in valid state.Set low to indicate the printer is off.

n.a. (nInit)Compatibility Mode: Pulsed low in conjunction with 1284 Active low to reset the

interface and force to return to Compatibility Mode idle phase.

Negotiation phase: Set HIGHReverse Data Transfer phase: Set HIGH

nDataAvail (NFault)Compatibility Mode: Set low to indicate that an internal printer error has

occurred.Negotiation phase: Set high to acknowledge 1284 compatibility.

In Nibble or Byte Mode it is then set low to indicate printer-to-host data is available following host setting HostBusy (nAutoFd) high.

Reverse Data Transfer phase: Nibble Mode: Set low to indicate that printer is ready to send to host.Then used to send data bits 0 then 4.

Byte Mode : Used to indicate that data is available.Reverse Idle phase : Used to indicate that data is available.


GENICOM 3460 / 3480 / 3480+ 8.11 GEK-89537

1284 Active (NSelectIn)Compatibility Mode: Set low by host to select printer.Negotiation phase: Set high in conjunction with Host Busy being set low to

request a 1284 mode.Reverse Data Transfer phase: Set high to indicate that bus direction is printer to host.

Set low to terminate 1284 mode and set bus direction host to printer.

Reverse Idle phase : Same as Reverse Data Transfer phase.

8.3 Serial Interface

The printers can optionally provide an additional board with a 25 pin connector with bothRS-232/C and RS-422/A electrical interfaces.Selection is done by Configuration Menu.

These interfaces support full-duplex connections only (no Line Turn Around procedure isavailable).

When the Reduced (LOCAL) Connection is selected, it is possible to exchange dataon either the RS-232/C or RS-422/A interface, according to selected type of interface.

When the RS-232/C interface is selected, the Full Connection can be used, with all itscontrol signals.

For remote connections, RS 232 C is required.

Since the RS-422/A interface does not support any control signal, the printers assumeall control signals of the EIA RS-232/C interface as being internally asserted to a positivelevel.

8.3.1.2 RS-232/C Signals Behaviour

These notes use the pin number for reference.

1 Frame GND (Shield)Shield can be optionally disconnected from the frame ground by means of a customer accessible jumper.

The printer is shipped with pin 1 connected to the frame ground (protective ground).

7 Signal ground This pin is the common 0 Volt of the power supply.

2 Transmitted data signal (an output from printer)A MARK condition is held during IDLE communication state.An indeterminate state is present when printer is powered off.

3 Received data signal (input) No fail safe circuit is present on this input signal.

The receive data selection feature must select this input to provide data to the printer.

4 Request to Send Signal (output) An ON condition is provided as long as Data Set Ready signal is found ON

(DSR is assumed always ON in Reduced Connection). It is held ON until printer is disconnected. An indeterminate output is present when printer is powered off.

5 Clear to Send (input) Full_Connection: Remote connection:

When ON this signal enables the data transmission to the Host (e.g. status, flow control characters etc.).

Direct connection to Host:Normally it is provided by the printer generated Request To Send signal via crossed wire connection in the cable.

Reduced_Connection: Printer assumes an ON condition for this signal.

6 Data Set Ready (input) Printer enables its reception and its transmission only if the ON condition is

found on this signal.

Full_Connection: Remote connection:

An ON condition indicates that Data Set is connected to the line.This does not always mean that the link is actually established, because it depends on the used type of data sets and network.Printer considers the ON condition as an actualized connection with the Host.Normally, when a Data Set is used on a switched or leased line, this signal going ON is an answer, after a certain time, to the printer Data Terminal Ready turned ON and viceversa. It is responsibility of the Host to make decisions


GENICOM 3460 / 3480 / 3480+ 8.19 GEK-89537

about the call establishment and printer availability. Hence, the printer will simply suspend its connection phase until Data Set Ready will turn ON after DTR is turned ON.


GENICOM 3460 / 3480 / 3480+ 8.20 GEK-89537

Direct connection to Host:Normally it is provided by the Host generated Data Terminal Ready signal via crossed wire connection in the cable.

Reduced_Connection: Printer assumes an ON condition for this signal.

8 Data Carrier Detector (input)

Full_Connection: Remote connection:

An ON condition on this signal indicates that Host modem issending the data carrier frequence (Host has turned ON its Request To Send).An OFF condition indicates either the Host is not sending itscarrier or the link line has been interrupted.

Direct connection to Host:Normally it is provided by the Host generated Request To Send signal by crossing the wire in the connection cable.

Reduced Connection: Printer assumes as ON condition for this signal.

11 2nd Request to Send Signal (output)

Functionally equivalent to Data Terminal Ready

20 Data Terminal Ready (output)

Remote connection: An ON condition of this signal indicates that printer is ready to

initiate a connection. Printer turns or confirms the ON condition on this signal every time is initialized. In turn, an ON condition is expected on the Data Set Ready signal.

Normally it is wired to the Host Data Set Ready signal by crossing the wire in the connection cable.

An indeterminate condition is present on this output signal when printer is powered OFF.

MARK In the range " 1 "(Stop) from -3V to -25V

DATASPACE In the range " 0 "(Start) from +3V to +25V

ON In the range " 1 "from +3V to +5V

CONTRLOFF In the range " 0 " from -3V to -5V

Signals between -3V and +3V must not be used since receivers assume anindeterminate output state.Drive capability: In accordance with RS-232/C Standard and CCITT-V28 Recommendation:the maximum assured distance is 50 feet (15m) for all supported data rates.

8.3.2 RS-422/A Interface

This interface is provided together with the full RS 232C on the same optional board anduses the same 25 pin connector: some of the pins are dedicated to each type ofinterface.

If the printer provides both RS-232/C and RS-422/A interfaces, when it is personalizedfor local connection it must be able to exchange data on either the RS-232C or RS-422/Ainterface with no distiction about which type of interface is used.

Since the RS-422/A interface does not support any control signal, the printer assumesall control signals of the EIA RS-232/C interface as being internally asserted to a positivelevel.

This interface is intended as a subset of standard RS 422 providing its basic signals andallowing the connection of printers at the same conditions as the competition.

This interface supports full-duplex local connections. Only data signals are provided in thisinterface.

Pin assignments refer to the same 25 pin connector also used for the RS 232-C interface.

8.3.3 Other Characteristics of RS-232/C & RS-422/A

### Transmission type: Asynchronous (start/stop) with serial bit data

### Data char. format: 1 Start bit + 8 Data bit + 1 Parity bit + 1 Stop bit.Number of data bits is selectable. The framing error reported onpaper is link and device protocol dependent.

### Bit trasmission : The least significant bit is sent first, parity bit followsthe data bits. Start and stop bits are character framing bits.

### Parity & P.check: The parity check is ODD/EVEN or MARK/SPACE orNO PARITY accordin to the selection. The parity errorreporting on paper is link and device protocol dependent. Parallel bit: The ability to avoid the presence of the parity

bit both in reception and trasmission is device dependent.

### Trasmitting gross: <2% of the bit time (i.e.printer sends the stopStart/Stop distorsion bit which edges can be shiftedat maximum + 2% degrees with respect to theirnominal position).

### receive margin: Better than 37% (i.e. printer samples the last bit of a 10 bit character in the range of + 13% around the nominal bit center of the received character)

### Data Bit Rate: 300/600/1200/2400/4800/9600/19200/38400 Bps.The bit rates actually provided are device dependent.

8.4 Link Protocols

8.4.1 DTR & 2nd RTS Data Flow Control

The data flow is controlled by the 2nd RTS interface signal on pin 11 of RS-232/C interface(25 pin connector)

Signal levels Low (negative) : if buffer is in HGL condition High (positive) : if buffer is in LGL condition

The DTR signal (pin 20) of this interface is driven with the same procedure of the pin 11.

When input buffer condition goes in the Medium Guard Level (MGL), DTR/2nd RTS is setOFF until the buffer condition recovers to Low Guard Level (LGL) again (see next figure).

Figure 8.4 DTR/2nd RTS Timing


GENICOM 3460 / 3480 / 3480+ 8.26 GEK-89537

8.4.2 Xon/Xoff Data Flow Control

The data flow is controlled via TX line.

The XON code (HEX. 11) is used to indicate that the printer is able to receive data.(It is sent also at Power-on after completion of initialization)The XOFF code (HEX. 13) is used to indicate that the printer is unable to receive data.

The XOFF code is sent when input Buffer is in the Medium Guard level (MGL) condition.The XOFF code is sent on every received character when input buffer is in the High GuardLevel (HGL).

The XON code is sent when the buffer is in the Low Guard Level (LGL) condition.The XON code is repeated every two (2) sec when no data are sent to the printer.

GENICOM 3460 / 3480 / 3480+ 8.28 GEK-89537

8.4.3 Buffer Management

The data transmission is conditioned by the buffer status.

Rx buffer is managed in a two guards mode and its state is reported through DATA FLOWCONTROL message.

A Medium Guard Level and a Low Guard Level can be defined in order to respectively stopand allow start of character transmission.

MGL (stop) condition is maintained valid until the buffer is emptied (by printing) up to theLGL, which in turn is maintained valid until the MGL is reached; i.e. a buffer filled withcharacters in number between MGL and LGL is declared MGL or LGL according to itspreceeding condition.

The value of LGL is the buffer size minus 528 characters (or the buffer size if it is lower thanthat value).The value of LGL is defined taking into consideration some customer applications where apack of 512 characters is sent to the printer without any intermediate check.

When Rx buffer overrides Medium-Guard-Level (64 byte less than Max buffer capacity),Interface enters BUSY State.

When Rx buffer, after printing, goes down to the Low-Guard-Level, Interface resumesREADY State.

ASF BLOCKS DIAGRAM

The ASF hardware is composed of two separate boards:

• Paper Stacker Board• ASF Board.

and up to five motors (with 3 ASF installed):

• Paper Stacker stepper motor which switches a metal plate to allow the correct loadingof the single sheet or the fanfold through it.

• ASF DC motor inside each ASF which loads the single sheet into the printer.

The first board is included in the STACKER assembly and connects, through its finger-typeedge and the stacker cable, the main board.

The second board is integrated in the ASF1 assembly and allows the connection ofthe DC motors

As described in chapter 3, the ASIC integrated circuit drives the mechanical optionconnector lines via its internal serial synchronous interface.

The blocks diagram of the STACKER/ASF option isa shown below.
