The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic 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 ipping 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 eld. 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 specied steps and
disconnect the power plug.
Caution:
Do not turn off the power switch when downloading is under way.

Feed Drive System
Overview
The machine punches holes in paper when the paper has been stacked in the nisher 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 reection type sensor for identication of a full state.
The following shows the motors and sensors used for punching operation:
Motor Description
Punch motor (M24) Drives the Rack slider
Sensor Description
Punch 2/3hole sensor (PS39) Detects the Rack 2/3hole position of the
slider
Punch 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 position
Punch front sensor (PS37) Detects the slider front/rear position
Punch chip case sensor (PS40) Detects the presence/absence of the punch
chip case
Punch chip case full sensor Monitors the state (full) of the punch chip

Moving the Paper
Inside 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.

specic 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.

Checking the Condition of the Punch Chip Case
The 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 reection 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.
