Application
This manual has been issued by Canon Inc. for qualied 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.
Corrections
This manual may contain technical inaccuracies or typographical errors due to improvements
or changes in products. When changes occur in applicable products or in the contents of this
manual, Canon will release technical information as the need arises. In the event of major
changes in the contents of this manual over a long or short period, Canon will issue a new
edition of this manual.
The following paragraph does not apply to any countries where such provisions are
inconsistent with local law.
Trademarks

Use of this manual should be strictly supervised to avoid disclosure of condential
information.
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.
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic 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.
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
saddle.
Set the cable/wire to the
cable guide or wire saddle.
Remove the screw.
Tighten the screw.
Turn on the 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.

Error Code
E270 (Error in the main scanning/sub scanning synchronization signal).
-0001 Sub scanning synchronization signal (VSYNC) is not properly transmitted from scanner
unit PCB (front side scanner unit), and this causes image failure or abnormal termination.
-0002 Sub scanning synchronization signal (VSYNC) is not transmitted due to the error in the
main scanning synchronization signal (HSYNC), and this causes image failure or abnormal
termination.
-0101 Sub scanning synchronization signal (VSYNC) is not properly transmitted from scanner
unit PCB (back side scanner unit), and this causes image failure or abnormal termination.
E280 (Communication error between reader controller PCB – scanner unit)
- 0001 If the communication is not started within the specied time between reader controller
PCB – front side scanner unit.
- 0101 If the communication is not started within the specied time between reader controller

■
Original exposure and scanning are performed by the integrated scanner unit of LED, mirror,
lens and reading sensor.
Light emitted from LED is reected by the original and reaches the reading sensor through
the 3 folding mirrors and 4 free curvature mirrors.
1. LED lamp unit
On LED lamp unit, the light is generated from the 2 LED lamp PCBs (LED chip: 54 pieces per
PCB).
Generated light is exposed to the original through the reection plate.
2. Free curvature mirror
Scanner unit is equipped with the 3 folding mirrors and 4 free curvature mirrors.
Free curvature mirror has symmetric facet in main scanning direction and asymmetric facet in
sub scanning direction against the optical axis.

Scanner Unit
■
For exposure and scanning of original, this equipment uses an integrated scanner unit
consists of the LED, the mirror, the lens and the reading sensor.
The light emitted from the LED is reected to the original, and then received by the reading
sensor through the 3 turndown mirrors and the 4 free curved mirrors.
a. LED lamp unit
The LED lamp unit emits light from 2 boards of LED lamp PCB (LED chip: 54 pc per board).
The emitted light is reected to the original through the reecting plate.
b. Free curved mirror
The scanner unit has 3 turndown mirrors and 4 free curved mirrors.
The free curved mirror is a mirror symmetric to the light shaft in main (horizontal) scanning
direction while dissymmetric in sub (vertical) scanning direction.
c. Reading sensor
The reading sensor performs scanning of image per image line.
The reading sensor has 4 lines (B/W, R, G, B), using 1 line (B/W) when scanning black/white
image and 3 lines (R, G, B) when scanning color image.
Error code
E301 (insufcient light intensity)
-0101 The light intensity during back side shading is lower than the standard level
