INTRODUCTION

The descriptions in this Service Manual are based on he following rules:1. In each chapter, the uses of the function in question and its relationship to electrical and

mechanical systems are discussed and the timing of operation of its associated parts isexplained by means of outlines and diagrams.In the diagrams, the symbol represents a mechanical path, while the symbol

with a name next to it indicates the flow of an electric signal.The expression “turn on the power” means turning on the power switch, closing thefront door, and closing the delivery door so that the machine will be supplied withpower.

2. In circuit diagrams (digital), a signal whose level is High is expressed as being ‘1’,while a single whose level is Low is expressed as being ‘0’; the level of voltage, how-ever, varies from circuit to circuit.The machine uses CPUs, whose internal mechanisms cannot be checked in the field,and, therefore, are not explained. In addition, the machine’s PCBs are not intended forrepairs at the user’s and, therefore, are explained by means of block diagrams: two typesare used, i.e., between sensors and inputs of PCBs equipped with a control or drive func-tion and between outputs equipped with a control or drive function and loads; in addi-tion, functional block diagrams are used at times.

Changes made to the machine for product improvement are communicated in the form ofa Service Information bulletin as needed. All service persons are expected to go through allservice documentation including the bulletins and be equipped to respond to the needs of thefield (as by being able to identify possible causes of problems).

T02-203-01



2.3.2 Detecting the Presence/Absence of an OriginalThe presence/absence of an original in the original tray is detected by the original place-

ment sensor (PI6). The detecting lever operates in conjunction with the light-blocking plate.When an original is placed in the original tray, the light from the photointerrupter isblocked, thereby causing the original placement sensor (PI6) to generate the original place-ment signal (SET).

F02-203-01

2.3.3 Detecting the Last OriginalThe last original sensor (PI1) and the registration sensor (PI7) are used to find out

whether or not the original being picked is the last original.When the last original has been picked up and its trailing edge moves past the last original

detecting lever, the detecting lever blocks the light of the photointerrupter while operating inassociation with the light-blocking plate. At this time, if the leading edge of the original is asfar as the registration sensor (PI7), the last original sensor (PI1) generates the last originaldetection signal (LENG1) to communicate to the host machine that the original in questionis the last from the stack in the original tray.

2.3.4 Detecting the Size of an Originala.Detecting the Length in Feed Direction

The length of an original in feed direction is detect by the length sensor 1 (PI1) and thelength sensor 2 (PI2). When an original is placed in the original tray, the detecting levers ofthese 2 length sensors operate in conjunction with the light-blocking plate to block the lightof the photointerrupter.

In mixed original size mode, however the length is detected based on the number of linesread by the scanner connected to it.

2.4 Picking Up and Separating an Original2.4.1 Basic Pickup Operation

When an original is placed in the original tray and the Start key is pressed, the machinewill go through the following sequence:

a.PickupWhen the electromagnetic clutch goes ON and the feed motor (M1) rotates clockwise, the

pickup roller moves down, and the separation roller and the pickup roller start to rotate topick up an original; then, the stopper moves up in conduction.

The pre-separation pad and the separation pad serve to prevent double feeding of origi-nals.

F02-204-01

b. FeedingThe rollers found beyond the pull-off roller rotate at a speed about 50% higher than the

separation roller. When the original reaches the pull-off roller, its movement grows faster,thereby causing the pickup roller and the separation roller to rotate in conjunction.

c. Stream Reading and DeliveryWhen the leading edge of the original reaches read wait position, the machine sends the

image leading edge signal to its host machine to start stream reading; thereafter, the deliveryroller operates to delivery the original.

In stream reading, the host machine’s scanner is fixed in place, and the original is movedover the scanner glass for scanning.

F02-204-03

d.End of Pickup for the 1st OriginalWhen the trailing edge of the original moves past the pickup roller, the pickup roller will

come into contact with the 2nd original. However, since the separation roller is pulled by the1st original at a higher speed than its drive shaft, the spring clutch mounted to the shaftslips, transmitting the drive and preventing the rotation of the pickup roller and, as a result,not picking up the 2nd original.

e.Picking Up the 2nd OriginalWhen the trailing edge of the original leaves the separation roller, the spring clutch trans-

mits the drive, causing the pickup roller to rotate to pick up the 2nd original.

F02-204-05

f. Returning the Pickup Roller to Standby PositionWhen the last original moves past the original sensor and a specific period of time passes

thereafter, the electromagnetic clutch goes OFF and the feed motor stops.When the electromagnetic clutch goes ON and the feed motor starts to rotate in reverse,

the pickup roller is returned to standby position, at the end of which the feeder motor andthe electromagnetic clutch goes OFF.

2.4.2 Separation/Pickup MechanismThe machine uses a single stepping motor to pick up, separate, and move originals. Its

pickup assembly is equipped with 6 spring clutches which operate in various ways in rela-tion to the direction of motor rotation as follows; the arrows in the diagrams indicates thedirection of rotation.

F02-204-07

a.SPCL 1 (preventing the pickup roller from moving down)In standby, the pickup roller must be kept in up position. While the pickup roller remain

in up position, its own weight tries to force the clutch shaft to rotate clockwise; this, how-ever, is prevented by the tightening of SPCL1, which makes a connection to the serials ofgears linked to the motor.

The drive occurring as a result of clockwise/counterclockwise rotation of the motor istransmitted to the shaft when the clutch goes ON, and the operation of the clutch is irrel-evant.

b. CPCL2 (separation roller/pickup roller drive; ascent/decent movement and upperlimit of pickup roller)

Motor in Clockwise RotationAs the spring clutch contracts, the pickup roller and the separation roller are driven; as a

result, the pickup roller is moved down to rotate.Motor Rotating in Reverse

The pickup roller is moved up, and is held in “escape” position. If the pickup roller comesinto contact with the feeder cover, the spring clutch loosens to serve as a limiter, therebypreventing damage.

e.SPCL4 (pickup roller descent movement, separation roller/pickup roller drive; one way)Motor in Clockwise Rotation

As the spring contracts, the pickup roller is moved down; at the same time, the separationroller and the pickup roller are driven in the direction of pickup. When paper is moved bythe pull-off roller, it picks up speed, pulling and causing the separation roller to rotate in re-sponse; at this time, the spring clutch expands so that the pickup roller drive shaft stops torotate, ultimately stopping the pickup roller.Motor in Reverse Rotation

The spring clutch loosens to cut the drive.

g.SPCL6 (pickup roller drive; one-way)Motor in Clockwise Rotation

The drive of the belt is transmitted to the pickup roller for rotation into pickup direction(in the direction that causes the spring to tighten). When the paper is moved by the pull-offroller, its speed increases, and the pickup roller is pulled by the paper to rotate in conjunc-tion. At this time, the spring clutch loosens, and the drive to the belt is cut.Motor in Reverse Rotation

The spring clutch loosens to cut the drive.

2.4.3 Sequence of Pickup Operation

F02-204-15

2.4.4 Pickup Unit and the StopperThe pickup unit consists of a pickup roller and a separation roller. When the Start key is

pressed or the original pickup signal arrives, the feed motor (M1) rotates to move down thepickup unit, and the pickup roller and the separation roller rotate to move the paper.

The stopper operates in conjunction with the pickup unit, and moves up. To preventdouble feeding at time of pickup, the separation pad and the separation plate are used tomake sure that sheets are separated.

2.4.5 Controlling the Feed Motor (M1)The following is a diagram of the circuit used to control the feed motor (M1). The pickup

motor is a 2-phase stepping motor, and the functions of the circuit include the following:• turning on and off the motor.• controlling the direction of motor operation.• controlling the speed of motor rotation.

F02-204-17

The motor driver (IC1) on the ADF driver PCB receives commands from the host ma-chine, and sends drive pulses to the pick motor.

The feed motor is a stepping motor, and it controls the direction and speed of rotation bychanging the order in which the drive pulses (MOTA, MOTA*, MOTB, MOTB*) are sentand the frequency.
