Introduction

The following rules apply throughout this Service Manual:1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer-

ence to the timing of operation.In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates thedirection of the electric signal.The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results insupplying the machine with power.

2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, how-ever, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessorsused in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of theDC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be com-municated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and beable to identify and isolate faults in the machine."

3.1 Basic Operation

3.1.1 Basic Operation0014-8491

The finisher is designed to deliver copies arriving from its host machine, and its modes of delivery include simple stacking, job offset, and staple.All operations involved in these modes are controlled by the finisher controller PCB, according to the appropriate commands from the host machine.

F-3-1

Memo: The term job offset refers to shifting each sorting job, separating a single stack into several stacks.

3.1.2 Overview of the Electrical Circuitry0014-8492

The finisher's sequence of operation is controlled by the finisher controller PCB. The finisher controller PCB is a 16-bit microprocessor (CPU), and is used forcommunication with the host machine (serial) in addition to controlling the finisher's sequence of operations.The finisher controller PCB responds to the various commands coming from the host machine through a serial communications line to drive solenoids, motors, andother loads. In addition, it communicates the finisher's various states (information on sensors and switches) to the host machine through a serial communicationscircuit.The ICs used on the finisher controller PCB are designed for the following:

Controls sequence of operations.Contains sequence programs.

Backs up adjustment values.Backs up initial setting data.

Communicates with the host machine and the saddle stitcher unit.

Generates 5V.

Generates 3.3V.

3.2 Feed Drive System

3.2.1 Overview0014-8493

This product consists of the Finisher unit and the Saddle Stitcher unit.The Finisher unit simply stacks sheets delivered from a host machine, offsets a stack job, or staples and delivers the sheets to the trays according to commandsdelivered from a host machine.There are three delivery methods.

F-3-3

F-3-4

3.2.2 Constraction of the Control System0014-8494

The copy sent from the host machine is delivered to the ejection tray, escape tray, or processing tray according to the ejection type. Job offset or stapling is per-formed, according to the instruction from the host machine, for copy delivered to the staple tray.When ejecting from the processing tray, rear end assist guide is used in addition to the stack ejection roller to eject the stack.The feed motor (M101), stack ejection motor (M102), rear end assist motor (M109), escape feed motor (M112), and inlet motor (M113) are step motors. Thesemotors are rotated forward or backward by the microcomputer (CPU) in the finisher controller PCB. The following three sensors are provided in the copy delivery path to detect the arrival or passing of copies. - Inlet sensor (PI103) - Delivery path sensor (PI104) - Escape tray path sensor (PI118)Also, each ejection tray has sensors to detect the presence of copy on the tray. First tray paper sensor (PI111) Second tray paper sensor (PI112)If the copy does not reaches or passes each sensor within prescribed time, the finisher controller PCB determines that the jam has occurred and stops the operation.Then it notifies the host machine that a jam has occurred. When all of the doors are closed after fixing the jam, the finisher checks whether copy is detected by anyof the above three sensors (inlet sensor, delivery path sensor, escape tray path sensor). If any of the sensors detects a copy, the finisher determines that the jam isnot fixed and sends jam processing signal to the host machine once more.

3.2.3 Paper Delivery Path0014-8496

There are three ejection paths to tray 1 and 2 depending on the ejection processing. There is only one paper ejection path to the escape tray.

When the equipment is set to non-sort, all copies are ejected through the following path.Stack ejection roller

F-3-7

This is the copy ejection path when the equipment is set to sort for paper size other than A4, B5, or LTR or when set to staple sort. Copies are delivered to theprocessing tray for aligning and stapling. Then they are ejected using the rear end assist.

This is the copy ejection path when the equipment is set to sort for A4, B5, or LTR paper size. Feed two sheets of paper to buffer (two or three sheets if 2-pointstapling). Then they are aligned and stapled in the processing tray and ejected. Even while stapling or offset is being performed, simultaneous stack ejection, whichsimultaneously ejects copies delivered to the buffer and post processed stack in the processing tray, is performed because copies are received continuously from thehost machine. The stack delivered from the buffer is ejected to the processing tray and the stack processed in the processing tray is ejected to the tray.Simultaneous stack ejection operation is described below for two A4 copies between stacks when the equipment is set to sort.

1) When the 1st paper reaches the switchback point, it is sent to the buffer unit and the rear end of the paper is held by the buffer guide.

F-3-92) When the first copy is delivered to the buffer, the second copy is delivered from the host machine.

3.2.4 Controlling the Change of the Gear0014-8497

The machine shifts down the gear of the inlet motor (M101) to suit the movement of paper (e.g., heavy paper in color mode) arriving from its host machine at 132mm/sec or slower, and the finisher controller PCB serves to control this mechanism.When the finisher controller PCB receives the operation start signal from the host machine, it turns on the gear change motor (M110) to switch from high- to lower-speed gear by way of the rack gear/2-step gear. The home position of the gear change motor (M110) is monitored by the gear change home position sensor (PI117).When a switchover has been made from high- to low speed gear, the finisher controller PCB drives the inlet motor (M101) to start delivery of paper. When thetrailing edge of paper reaches the buffer assembly, the machine stops the paper once, and drives the gear change motor (M110) to switch over from low- to high-speed gear. Thereafter, the machine performs normal stacking operation for the paper.

3.3.1 Stack Job Offset0014-8498

Job offset operation offsets paper stack to the front or rear when ejecting to sort the paper stack.The forward/backward movement of the copy delivered to the processing tray is controlled by the front aligning plate and rear aligning plate.The aligned copies are stapled or ejected according to the signal from the host machine.When the power is turned on, the finisher controller PCB drives the aligning plate front motor (M103) and aligning plate rear motor (M104) to return the two align-ing plates to home position.The name and function of motors and sensors used by the stack job offset function are shown below.

3.3.4 Rear End Assist Operation0014-8501

In order to improve stacking performance when ejecting copies delivered to the processing tray, a rear end assist guide is used in addition to the stack ejection rollerto support the rear end of the stack during stack ejection.

F-3-21

3.3.5 Stack Delivery Operation0014-8503

The stack is ejected each time three large size sheets*1 or five small size sheets*2 are offset on the processing tray.The swing motor turns and the swing guide descends. This causes the upper/lower stack delivery rollers to hold the stack. The stack delivery motor turns the stackdelivery roller and return roller. At the same time, the rear end assist guide is started by the rear end assist motor and the stack held by the stack delivery rollers isdelivered in the ejection direction. The rear end assist guide stops once it reaches the prescribed position and returns to home position when the rear end assist motoris reversed. Then the stack delivery motor starts and ejects the stack with the upper/lower stack delivery rollers.

In case for the thick paper, copy stack always consists of 2 sheets.*2 Varies from 1 to 6 sheets depending on the number of original. (ex: When the number of original is 7, copy stack are ejected in the order of 5 sheets and 2 sheets.)

3.3.6 Swing Height Detection Control0014-8504

A. OverivewNormally, the color-printed paper is ejected to the process tray with it rubbing against the paper loaded in the process tray, causing scrathes on the printed image.To prevent this, the swing unit height is controlled.B. Description of ControlWhen paper is ejected to the processing tray, the height of the swing unit [3] is detected with the swing height detection sensor [1] and swing height detection sensorflag [2] in order to stop the swing unit [3] at the appropriate position, thus reducing scratches on color prints.

3.4 Staple Operation

3.4.1 Stapler Unit0014-8505

The staple motor (M111) is used to perform stapling operation. This motor rotates the cam one turn for stapling. The home position of this cam is detected by thestaple home position sensor (PI50).The staple motor is rotated in the forward or reverse direction under the control of the macro computer (IC108) on the finisher controller PCB.When the staple home position sensor is OFF, the finisher controller PCB rotates the staple motor in the forward direction until the sensor turns ON, allowing thestaple cam to the original position.The staple sensor (PI52) is used to detect presence/absence of a staple cartridge in the machine and presence/absence of staples in the cartridge.The staple edging sensor (PI51) is used to determine whether staples are pushed up to the top of the staple cartridge.The finisher controller circuit does not drive the staple motor (M111) unless the staple safety switch (MSW104) is ON. This assures safety in case where you happento put your finger in the stapler.
