INTRODUCTION

The following rules apply throughout this document:As a rule, the descriptions in this documentation are based on the following:1. As needed, the work of each function and its relationship with electrical and me-

chanical parts are explained; where applicable, the timing at which associated partsare driven are also outlined.In a diagram, the symbol indicates a path of mechanical drive; the symbol

accompanied by a notation indicates the flow of an electrical signal.The expression “power-on” means turning on the power switch, closing the frontdoor, and closing the delivery door so that the parts of the machine are supplied withpower.

2. In a digital circuit, the state of a signal is indicated by ‘1’ if its voltage level is highand by ‘0’ if low. The level of voltage, however, differs from circuit to circuit.The machine uses a CPU; however, since the internal functions of a CPU is outsidethe scope of a service person, detailed explanations are omitted from descriptions. Inthis document, a circuit diagram may cover from sensors to inputs of a controllerPCB or from outputs of a controller PCB to loads, or it may be a functional diagram.

The descriptions of the machine are subject to change for product improvement, and ma-jor changes will be communicated in the form of Service Information bulletins.

All service persons are expected to be fully familiar with the contents of this ServiceManual and Service Information bulletins to develop a good understanding of the machine,equipping themselves with the ability and skill to identify faults and to maintain the machinein good order.

2.3.2 Detecting the Presence/Absence of an OriginalThe presence/absence of an original on the original tray is checked by the original set sen-

sor (PI5).When an original is placed on the original tray, the detecting lever operates in conjunction

with the light-blocking plate, which blocks the light of the photointerrupter, causing theoriginal set sensor (PI5) to generate the original detection signal (DTS). The ADF controllerPCB turns on the Original Set indicator in response to the original detection signal (DTS).

2.3.3 Initial Original Size Detection (feed direction)The initial original size detection (feed direction) mechanism is executed using the large/

small identification sensor (PI3) designed to find out whether the original on the originaltray is of a small size or a large size. In addition, it serves to distinguish between LTRR andLGL during last original size detection.

When a large-size original is placed on the original tray, the detecting lever operates inconjunction with the light-blocking plate, which blocks the light of the photointerrupter,causing the machine to identify the original as being of a large-size and send the result ofdetection to its host machine.

The result is based on real-time detection, and is sent to the host machine at 100-msec in-tervals.

2.3.4 Initial Original Size Detection (breadthwise)a.Outline

The initial original size detection mechanism for the breadthwise direction of an originalis performed by the original width detecting volume (VR1) located inside the original tray.

The original width volume operates in conjunction with the slide guide, and the resis-tance shows analog fluctuations. The ADF controller receives the fluctuations in resistancein the form of the original size signal (WIDTH), and converts it to a breadthwise size.

The A4R/LTRR identification sensor (PI4) is used exclusively to enable the originalwidth detecting volume (VR1) to accurately detect the width of A4R (210 mm wide) andLTRR (216 mm wide).

The A4R/LTRR identification sensor generates the A4R/LR identification signal (‘1’)when the width of an original is 197 mm or more and less than 214 mm.

T02-203-03

If the width of an original is not any indicated in the table at power-on yet is between 140and 297 mm, the next largest size will be selected.

For instance, if the width is a non-default width of 236 mm, the default width of 238 to267 mm will be selected. If a non-default width is identified except at power-on, the defaultwidth before a shift is made to a non-default width will be used.

The machine will select a default size based on the “width of the original” detected by ini-tial original size detection and the “length of the original,” and communicates the result tothe host machine.

b. Slide Guide Positioning RollThe rail of the slide guide is provided with a groove so that the guide may stop at any of

default size positions. The stop positions, however, are closely located for some papersizes, possibly stopping the guide at the wrong point.

The machine comes with two slide guide positioning rolls to enable a change of stop po-sitions so that the slide guide may be stopped at the positions shown in the following table.

2.3.5 Last Original Size DetectionThe last original size detection mechanism is executed by the post-separation sensor (S3).The last original size detection mechanism takes place when the original is held in read

wait position. The mechanism uses the width detected by the initial original size detectionmechanism using the original width volume (VR1), and uses the post-separation sensor (S3)to find out the length of the original.

If the original is large size, the post-separation sensor (S3) emits light in response to thereference intensity adjustment signal (SEPAJ), and its light-receiving segment detects thelight reflected by the original, and sends the original detection signal (P-SEP) to the ADFcontroller PCB.

2.3.6 Checking Originals When Printing Originals of Different Widths or inExtra-Length Mode

When printing originals of different widths or in extra-length mode, the originals are iden-tified as being large size or small size with reference to the state of the post-separation sen-sor (S3) with an original held in read wait position. The detection is based solely on thelength of the original, and is executed within the feed path.

a.Post-Separation Sensor (S3) Is Off (small size)The distance over which the original has moved is checked based on the number of

clock pulses from the feed motor (M2) between when the post-separation sensor turns off(passage of the trailing edge) and when the original is held in wait position.

b. Post-Separation Sensor (S3) Is On (large size)The distance of feed is detected based on the number of clock pulses from the feed mo-

tor (M2) between when the read sensor (S2) turns on and the read sensor (S2) turns off.

2.4 Original Pickup/Separation2.4.1 Basic Sequence of Pickup Operations

When the Start key is pressed while originals are placed on the original tray, the followingtakes place to pickup up the originals:

a.PickupThe pickup motor (M1) rotates in reverse, and the pickup clutch (CL1) turns on. As a

result, the stopper and the pickup roller unit move down to rotate the pickup roller. Theseparation plate and the separation pad are used to prevent double-feeding of originals.

F02-204-01

b. ArchingThe pickup motor (M1) is stopped so that the original is butted against the registration

roller and is made to arch, thereby removing any skew.

F02-204-03

d.Stream ReadingWhen the leading edge of an original reaches read wait position, the image leading edge

signal is sent to the host machine to start stream reading, in which the host machine’s scan-ner is held in place and originals are slid over the copyboard glass for scanning. The re-sults of reading are stored in the host machine’s memory.

2.4.2 Pickup Unit and StopperThe pickup unit consists of a pickup roller and a feed roller. When the Start key is pressed

or the original pickup signal is generated, the pickup motor (M1) starts to rotate in reverse,and the pickup clutch (CL1) turns on.

At the same time, the stopper and the pickup unit move down, and the pickup roller andthe feed roller rotate to move the original. To prevent double-feeding, the separation pad andthe separation plate are used to ensure proper separation.

2.5 Reversal2.5.1 Operations

The reversal mechanism operates to turn over originals from their first side to their secondside or from their first side to their second side; these two operations are virtually identical,and the discussions that follow are based on turning originals from their first side to theirsecond side.

a.Picking Up the 1st SideThe feed roller rotates using the drive of the feed motor (M2), and the 1st side is read.

To move the original, the delivery reversing roller rotates using the drive of the deliveryreversal motor (M3), and the original is moved to the delivery assembly.

The locking solenoid (SL2) turns on in reference to the end of reading operation, and thedelivery reversing roller becomes locked to let the original move.

F02-205-01

b. Reversal/Feed 1When the trailing edge of the original moves past the delivery reversal sensor (S1), the

delivery reversal motor (M3) stops. Immediately thereafter, it starts to rotate in reverse tomove the original to the registration roller 2.

The following figure shows an outline of the machine’s power supply system.The machine’s power supply receives two type of 24V power (24 VP, 24 VL) from its host

machine.The 24VP supply is mostly used for loads, and is cut off when the upper cover is opened.If an overcurrent starts to flow into the circuit, the circuit breaker (CB1) will turn on to

cut the power supply, thereby protecting the circuit.The 24VL supply is converted to 5V power by the IC11, and is sent to sensors and is also

used to drive the controller PCB.

5 Self Diagnosis

5.1 OutlineThe CPU on the machine’s ADF controller PCB is equipped with a mechanism to run self

diagnosis. If it detects a fault, it will indicate the fact by the LEDs on the ADF controllerPCB, and send a code to the host machine to indicate the nature of the fault.

The data may be any of three types, and the nature of the error may be checked by refer-ring to the Original Set indicator or the LEDs on the ADF controller PCB. Normally, LED4flashes at intervals of 250 msec.

Error Original set indicator LEDsAlarm Flashes at intervals of 240 msec Flashes at intervals of 240 msec.

For details, see p. 5-41Jam Flashes at intervals of 160 msec Flashes at internals of 160 msec.

For details, see p. 2-38.Error Flashes at intervals of 80 msec Flashes at intervals of 80 msec.

For details, see p. 5-42.
