Application
This manual has been issued by Canon Inc. for qualied persons to learn technical theory,
installation, maintenance, and repair of products. This manual covers all localities where the
products are sold. For this reason, there may be information in this manual that does not
apply to your locality.

Explanation of Symbols
The following symbols are used throughout this Service Manual.
Symbols Explanation Symbols Explanation
Check. Remove the claw.
Check visually. Insert the claw.
Check the noise. Use the bundled part.
Disconnect the connector. Push the part.
Connect the connector. Plug the power cable.
Remove the cable/wire
from the cable guide or wire

Turn on the power.
Set the cable/wire to the

Remove the screw.
Tighten the screw.
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.

Outline of basic operation
Non-sort operation
1.Outline
Ejected paper from the host machine is aligned and stacked on the processing tray. Paper
stack is then ejected on the stack tray. The paper stack is placed at the center in cross
feeding direction.
2.Details
Outline of operation
1)Ejected paper from the host machine is conveyed into the nisher.
2)Before paper trailing edge passes by the entrance roller, the shift roller goes down to press
the paper. After the trailing edge passes by the entrance roller, the shift roller stops turning.
3)The gripper opens and the shift roller reverses to transport the paper stack to the aligning
plate.
4)The shift roller goes up to release the paper stack and the gripper closes to grip the stack.
5)The above steps repeat themselves up until the number of the paper on the processing
tray becomes 10 (1 for the envelope) or the operation complete signal is issued whichever
comes rst.
6)Gripper starts to eject the paper stack on the stack tray.
7)Stack height detection lever moves up to evacuate itself and moves down again to detect
the stacking height when the stack ejection has completed.

Offset operation
1.Outline
Stacking the ejected paper from the host machine onto the processing tray. Every paper
stack consisting of 10sheets of paper is offset and ejected on the stack tray.
2.Details
Outline of operation
1)1)through 5) are the same operation as "Non-sort".
6)The shift roller moves to the center or rear-end position and align the paper stack to locate
it at specied shift position.
7)The shift roller goes up to release the paper stack and the gripper closes to grip the stack.
8)The shift roller returns to its idle position and the above steps repeats themselves till the
last paper.
9)Gripper starts to eject the paper stack on the stack tray.
10)Stack height detection lever moves up to evacuate itself and moves down again to detect
the stacking height when the stack ejection has completed.。

Stapling operation
1.Outline
Stacking the ejected paper from the host machine onto the processing tray. Stapling and
ejecting the paper stack on the stack tray.
2.Details
Outline of operation
"Angle stapling at 1 front corner", "Angle stapling at 1 rear corner" and "Double stapling (side
stitching)"
1)1) through 7) are the same operation as the offset operation.
2)Gripper conveys the paper stack to the stapling position with holding the stack.
"The operation 9) and 10) are applicable only to the front/ rear corner stapling."
9)After stapling the paper stack, the gripper starts to eject the stack on the stack tray.
10)At the same time, the stacking height detection lever moves up. The detection lever
moves down when the paper stack has ejected on the stack tray to detect the paper.
"The operation 9)' through 18) are applicable only to the double stapling (side stitching)."
9)The shift roller moves down and gives higher pressure to the paper stack. Gripper then
opens and evacuates itself to the connecting position with the stapler.

Customer maintenance
Cleaning the offset roller
Details
Offset roller should be cleaned once a month to maintain the accuracy of the stacking
alignment as foreign articles like dust are likely to stick to the roller.
[1]
Instruction
1) With holding up the roller a little, rub off paper dusts, etc. by a moist cloth.
MEMO:
If the optional tray is installed, it is easier to clean the rollers just after delivering a paper
onto the optional tray since the optional tray gets descended lower than the rollers.
Version Upgrade
Upgrade the rmware of the nisher controller according to the upgrade procedure
described in the service manual of the host machine.
This nisher does not support upgrading via downloader PCB (FY9-2034).
