Introduction

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

trical and mechanical systems with reference to the timing of operation.In the diagrams, represents the path of mechanical drive; where a signal name accompanies thesymbol, the arrow indicates the direction of the electric signal.The expression "turn on the power" means flipping on the power switch, closing the front door, and closingthe delivery unit door, which results in supplying 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 usedto indicate "Low".(The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) asin "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 microprocessors used in the machines are not discussed: they are explainedin terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCBto the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or otherpurposes, and major changes will be communicated 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 allrelevant Service Information bulletins and be able to identify and isolate faults in the machine."

In original size detection 1, the original trailing edge sensor is used (S7), which is designed to identify theoriginal in the original tray as being small-size or large-size.When the original covers the original trailing edge sensor, the light from the LED of the original trailing edgesensor is reflected by the original to hit the phototransistor, at which time the DADF identifies the original asbeing large-size.The DADF sends original size data (small-size or large-size) to the copier, which uses the data to determine thepoint at which the scanner is stopped for stream reading.

3.3.4 Original Size Detection 20013-3471

A. OutlineIn original size detection 2, the original width detecting switch (SW301) and the registration roller clock sensor(PI5) are used to identify a default size.The original width detecting switch is designed to find out the width of originals. As many as five contact plates(SSW0 through 4) are in contact with the original width detecting switch, operating in keeping with the slideguide. The state (ON or OFF) of each contact plate is communicated to the ADF controller PCB, which uses theinput to determine the width of the original.The following table shows the states of the contact plates in relation to default sizes; the states other than thoseindicated are assumed to indicate the presence of an original which is not of a default size.

The registration roller clock sensor (PI5) is used to measure the length of originals with reference to therevolutions made by the clock plate mounted to the slave roller of the registration roller. Based on therevolutions of the lock plate, the ADF controller PCB identifies the length of the original in question (in feedingdirection).

F-3-17

The DADF uses the data on the width and the length of the original obtained by original detection 2 to identifya default size, and sends the result to the copier. In response, the copier selects the appropriate copy paper sizeto suit the identified size of the original.The following tables show the default sizes in relation to the sizes detected by the DADF:

B. Slide Guide LockThe DADF is equipped with a slide guide lock so that the slide guide will not slide beyond the width of an A4/A3 sheet.To use an original wider than 297 mm, remove the slide guide lock (up to 305 mm; however, the feeding lengthmust be 432 mm or less).

F-3-18

Be sure to adjust the slide guide to suit the original size when making copies.Otherwise, the original is likely to move askew.

C. Slide Guide Positioning MemberThe rail of the slide guide is provided with notches to make sure that the slide guide stops to suit a specificdefault original size. Some of these points representing differing paper sizes, however, are close enough to allowthe slide guide to be set at the wrong point.To prevent wrong positioning of the slide guide, the DADF comes with two types of slide guide positioningmembers; when fitted correctly, the positioning members will make sure that the slide guide will stop at thecorrect point.

3.4.3 Switching the Separation Pressure0013-3480

The DADF's separation assembly is equipped with a separation pressure switching mechanism which enablesswitching between two settings (low or high).The separation pressure may be switched by operating the separation pressure lever located in front of theseparation assembly. When the lever is operated, the position of the separation belt moves up or down to changethe amount of overlap in relation to the feeding roller, thereby varying the separation pressure.

MEMO:The separation pressure lever is set to "Low" at time of shipment from the factory.

3.4.4 Separation Sensor (S4) and Skew Sensor (S5)0013-3481

The paper path is equipped with a separation sensor (S4) and a skew sensor (S5) to monitor the movement oforiginals for the following:

A separation fault (delay) is identified if the separation sensor does not detect an original a specific period oftime after the separation motor has started to rotate.

F-3-28

Both separation sensor and skew sensor are used to find out whether an original is moving askew. These twosensors are arranged in a single row in front-rear direction. An original is identified as moving askew if adiscrepancy in timing is detected when it moves past these sensors. If the discrepancy is an equivalent of 10 mm,the DADF will assume that the original is moving askew, at which point it stops its operation to protect theoriginal and causes the copier to indicate a jam message.

3.4.5 Controlling the Pickup Motor (M3)0013-3482

The following is a diagram of the circuit used to control the pickup motor (M3).The pickup motor is a 4-phasestepping motor, and has the following mechanisms:- turning on/off the motor- controlling the direction of motor rotation- holding the motor at rest

F-3-29

[1] ADF controller PCBM3: pickup motor

The CPU (IC18) sends phase control signals (PICKA, PICKB, PICKA*, PICKB*) to the motor driver (IC31).In response, the motor driver controls the output timing of the pulse signals accordingly, switching over thedirection of motor rotation.PICKI0/PICKI1 is a current setup signal, and its variation (combination) enables a switch-over among 4 steps(from 0 % to 100 %). PICKSTBY is a motor standby signal, and is used to turn off the motor drive circuit, duringwhich time no phase signal is sent to the motor.

Error code: E410- fault in the pickup motor (M3)- fault in the pickup roller height sensor (PI8)- fault in the pickup roller height sensor (PI9)- fault in the pickup roller home position sensor (PI7)- fault in the ADF controller PCB

The following is a diagram of the circuit used to control the separation motor (M4). The separation motor is aDC motor, and the circuit has the following functions:- turning on/off the motor- controlling the speed of the motor- protecting the motor against overcurrent

F-3-30

[1] ADF controller PCB[2] Current detection circuitM4: separation motorMI2: separation motor clock sensor

When the CPU sends the motor rotation speed signal (SPPWM), the separation motor (M4) starts to rotate in aspecific direction. The separation motor clock sensor (PI2) sends the separation motor rotation speed signal(SPCLK) to IC17 (speed control IC). In response, IC17 compares the arriving rotation speed signal against thespeed reference signal (SEPCLKREF) from the CPU, and sends the result as the speed control signal (SPMFV)to the CPU. Using the arriving speed control signal, the CPU varies the rotation speed signal. LED3 goes onwhen the motor rotation speed is within a specific range, while going off if out of the range. The currentdetection circuit monitors the current flowing in the separation motor; when the level of the current exceeds aspecific value, it sends the separation motor stop signal (SPLIM) to stop the motor. The CPU identifies a faultin the separation motor if the separation motor stop signal continues, indicating an error code (E405) on the hostmachine's display.

3.6.7 Manual Feeder Pickup/Delivery Operation0013-3518

The machine uses 'manual feeder pickup/delivery' only for fixed reading mode.1) When an original is placed in the manual feeder, the manual feeder placement sensor (PI12) detects it.

F-3-114

2) When the Start key is pressed, the machine uses the delivery roller to move the original until the lead edge ofthe original butts against the manual feeder registration roller (thus removing the skew).

F-3-115

3) The machine moves the original to move the delivery roller and the transport belt. The original stops whenits lead edge reaches the reversal sensor (S1).

F-3-116

4) The machine rotates the transport belt. The original is moved over a specific distance after its trail edge hasmoved past the reversal sensor (S1), and is then stopped.

3.7 Detecting Jams

3.7.1 Overview 0013-3519

The machine checks for jams using the following sensors. The CPU on the ADF controller PCB runs a check atsuch times as programmed in advance, and detects the presence/absence of a jam in relation to the presence/absence of paper over a specific sensor.Upon detection of a jam, the machine communicates the fact to the host machine, which in turn indicates thefact in service mode in the form of a code. A check may also be made with reference to the indicator (DSP1) ofthe machine's ADF control PCB.

3.8 Power Supply

3.8.1 Overview0013-3523

The following is a diagram of the machine's power supply system:The machine is supplied with 24V and 13V power by its host machine. The 24V power is supplied to variousloads by way of a circuit breaker (CB1). Of the 24V power supplied to the loads, 24U is sent by way of a fuse,while 24R is sent directly.The 13 V power is converted into 5 V for sensors by a regulator IC (IC15). Another regulator IC (IC26) is usedto convert 5 V into 3.3 V, which is used to drive the ADF controller PCB.
