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.
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.

Caution
Use of this manual should be strictly supervised to avoid disclosure of condential
information.

Explanation of Symbols
The following symbols are used throughout this Service Manual.
Symbols Explanation Symbols Explanation
Used to show permission. Remove the screw.
Used to show prohibition. Tighten the screw.
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
saddle.
Turn on the power.
Set the cable/wire to the
cable guide or wire saddle.
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.

Characteristics
●Small and low-cost printer
The printer uses a at in-line cartridge method for the rst time in the small printer. This
lowers the height and reduces the printer size. The printer uses the transfer pad and the
separation roller to reduce the parts expenses.
●Intermediate transfer method
The intermediate transfer method transfers toner images to the Intermediate Transfer Belt (ITB)
and transfers the images in four colors onto the print media at once. It realizes a stabilized
color-print on various media without being affected by the primary transfer operation.
●Improved usability
The printer improves usability by using the pullout cartridge and the front side accessibility to
the media. This small-sized printer is user-friendly on the space of the desktop.

Safety Precautions
Safty of the Laser Light
Laser beam radiation may pose a danger to the human body. A laser scanner mounted on the
machine is sealed with the protection housing and external cover to prevent the laser beam
from leaking to the outside. The laser beam never leaks out of the scanner as far as users
operate the machine normally
The following warnings are given to comply with Safety Principles (EN60950).
Laserstrahlen können für den menschlichen Körper gefährlich sein. Aus diesem Grund ist das
optische Lasersystem mit einem Schutzgehäuse und einer Außenabdeckung
dicht verschlossen und hat eine Struktur, die keine Laserstrahlen nach außen dringen lässt.
Unter der Voraussetzung, dass der Benutzer dieses Gerät normal
bedient, ist ein Austritt von Laserstrahlen daher ausgeschlossen.
Safety of Toner
■Toner in General
Toner is a non-toxic material made up of plastic, iron, and small amounts of dye.
Caution :
Do not throw toner into re. Doing so can lead to explosion.
■Contact with Toner
• Toner on the skin or clothes must be removed using dry tissue and then washed with
water.
• The use of warm water must be avoided, doing so will cause the toner to turn gel-like and
to permanently fuse with the bers of the clothes.
• Contact with vinyl must also be avoided, as toner can readily react.
■Store of Copy/Print Output
• Be sure to use transparency cases for storing copy/print output.
• Do not use transparency cases made from polyvinyl chloride materials. If the copied
surface contacts to the case, toner on the surface of the output dissolves and the output
may adhere to the case. .
Handling the Laser Unit
When servicing the area around the laser assembly, be sure to turn off the main power.
If you must servicr while the power is turned on, be sure to keep the followings:
• Do not use a screwdriver or tools that have a high level of reectance in the laser path.
• Remove watches and rings before starting the work. (They can reect the laser beam,
possibly hitting the eye.)
The machine's covers that can reect laser light are identied by means of a warning label
(Figure). If you must detach a cover showing the label, be sure to take
extra caution during the work.
The following warnings are given to comply with Safety Principles (EN60950).

Points to note at disassembly/installation procedure
At disassembly/installation procedure, make sure to follow the instruction below to proceed.
1. Be sure to unplug the power code before disassembly/installation.
2. At installation, follow the procedure in the reverse order of disassembly unless otherwise
instructed.
3. Be careful of the screw type (length, diameter) and corresponding part.
4. To check the electrical conductivity, washer equipped screw is used to attach the grounding
wire and the varistor etc. When attaching them, be sure to use this
screw.
5. In principle, do not operate the machine without any part.
6. Be sure not to unscrew the screw with painting at disassembly.
