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 reference to the timing of operation.

In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, 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 closing the 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 used to indicate "Low". (The voltage value, however, 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 microprocessors used 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 the DC 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 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 all relevant Service Information bulletins and be able to identify and isolate faults in the machine.

Notes Before Servicing

Caution:

At servicing, be sure to turn off the power source according to the specified steps and disconnect the power plug.

Caution:

Do not turn off the power switch when downloading is under way.

Turning off the main power switch while downloading is under way can disable the machine.

Points to Note at Cleaning

Caution:

When performing cleaning using organic solvent such as alcohol, be sure to check that the component of solvent is vaporized completely before assembling.

Feed Drive System

OverviewThe machine punches holes in paper when the paper has been stacked in the finisher and stopped.When paper arrives from the host machine, the shift roller starts to move it ahead; the shift transport motor then moves the paper back to the puncher unit and forces its trail edge against the stopper to remove the skew to prepare for punching operation.The chips occurring as the result of punching are collected in the punch chip case, which is monitored by a reflection type sensor for identification of a full state.The following shows the motors and sensors used for punching operation:

Motor DescriptionPunch motor (M24) Drives the Rack slider

Sensor DescriptionPunch 2/3hole sensor (PS39) Detects the Rack 2/3hole position of the

sliderPunch clock sensor (PS38) Monitors the speed of punch motor rotation

and timing at which the slider movement is stopped

Punch motor home position sensor (PS36) Detects the Rack positionPunch front sensor (PS37) Detects the slider front/rear positionPunch chip case sensor (PS40) Detects the presence/absence of the punch

Technology > Feed Drive System > Moving the Paper

Moving the PaperInside the machine, paper is moved as follows:

1) When the inlet sensor (PS3) detects the lead edge of paper, the horizontal registration detection unit shift motor (M6) goes on to move the horizontal registration detection unit to the point of paper detection.

2) When the inlet sensor detects the lead edge of paper, the machine moves the paper over a specific distance and then uses the shift transport motor to drive the shift roller.

4) After correcting displacement in horizontal registration, the machine uses the shift transport motor to move the paper back to the punch unit and, at the same time, executes full horizontal registration, in which the edge of the paper hits the stopper mounted to the punch unit. The machine is now ready for punching.

5) At the end of punching, the machine uses the shift roller for delivery of the paper.

Checking the Condition of the Punch Chip CaseThe punch chip case detection mechanism consists of the punch chip case full sensor mounted to the side of the punch chip case and a prism found inside the case.The punch chip case sensor, on the other hand, is used to check the presence/absence of the punch chip case.The chips occurring as the result of punching operation are collected in the punch chip case, and are monitored by a reflection type sensor (punch chip case full sensor). When the case becomes full with chips, the main controller PCB suspends punching operation between stacks (Memo), resuming the operation when the case is put back in place.

NOTE: If the punch chip case is found to be full when the 2nd sheet of the 3rd set is being handled while making 5 sets of 5 copies, the machine continues to operate until the 3rd set is complete, suspending its operation at the start of the 4th set.
