written consent of Canon Inc.

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

Used to show permission.

Used to show prohibition.

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.

High-Speed Color Printer

●

This machine is a high-speed color printer, realizing a speed of approximately 30 pages per

minute in full-color printing with A4 vertical paper.

Introducing Intermediate Transfer Method (ITB)

●

This machine introduced an intermediate transfer method, in which 4-color toner images are

transferred into an intermediate transfer belt (ITB) and then simultaneously transferred into a

printing sheet. This method enabled to realize stable color printing in various types of paper

without receiving impact of paper at the time of primary transfer.

Safety Precautions

Laser Safety

Laser beam radiation sometimes causes a danger to human body. To prevent such a danger,

the optical laser system used in this machine is hermetically closed by the protection housing

and external cover so that a laser beam does not leak to outside. Therefore, a laser beam

does not leak out of this machine as long as a user operates the machine in an ordinary

manner.

CDRH Regulation

CDRH (Center for Devices and Radiological Health), which belongs to Food and Drug

Administration in USA, put a regulation concerning laser products on August 2, 1976. This

regulation is applied to laser products manufactured on and after August 1, 1976, and sales

activities are prohibited in USA without receiving permission under the regulation.

The following gure shows the label indicating that permission has been received under the

CDRH regulation, and it is obliged to attach it on all products sold in USA.

Toner Safety

About Toner

■

Toner is a nontoxic substance which consists of plastic, iron, and a small amount of pigment.

Caution :

Be sure not to throw toner into the re. Doing so may cause an explosion.

How to Handle Adhered Toner

■

When toner adhered to skin or clothes, completely remove it with dried tissue and wash

•

with water.

If hot water is used, toner cannot be removed because it becomes gel and penetrates into

•

clothes permanently.

Do not make toner come into contact with vinyl because it easily reacts with a vinyl

•

material.

How to Handle the Laser Scanner Unit

An invisible laser beam is irradiated in the laser scanner unit.

If the laser beam enters an eye, it may cause damage to the eye. So, be sure not to

disassemble the laser scanner unit. No adjustment can be made to the laser scanner unit in

this machine in the eld.

The label shown in the following gure is attached to the bottom of the laser scanner unit.

Points to Note when Replacing/Discarding a Lithium

Battery

The main controller PCB in this machine contains a lithium battery as backup power supply

for various data just in the case when a blackout occurs or the power plug is removed.

Caution :

If the battery is replaced with an incorrect type of battery, it may cause an explosion.

Points to Note when Performing Disassembly/Assembly

Be sure to follow the instruction shown below when performing disassembly/assembly.

1. Be sure to unplug the power plug for safety when performing disassembly/assembly.

2. If not otherwise specied, perform assembly in the procedure opposite to that of

disassembly.

3. Perform assembly using correct types of screws, etc. (length/diameter) at correct positions.

4. A washer screw is used as a screw to x a grounding wire and varistor, etc., to secure

electrical conduction. Be sure to use this screw when performing assembly.

5. In principle, do not operate the machine in the condition where parts are removed.

6. Do not remove a paint-locked screw when performing disassembly.

Laser Exposure System

Overview

The laser exposure system forms a latent image on the photosensitive drum according to the

video signal sent from the main controller.

The laser scanner unit consists of the laser unit and the scanner motor unit. Each unit is

controlled by the signal entered from the DC controller.

Two laser scanner units are used in this machine. One is a unit for Y/M, and the other is for

C/Bk, which are common units.

One laser scanner unit consists of the laser drive unit, which controls the laser unit, and the

scanner motor unit, which controls the scanner motor. One scanner motor and scanner mirror

reect laser beams for two colors.

These parts are contained in the laser scanner unit and controlled by the DC controller.

The DC controller irradiates each laser beam according to the video signal received from the

main controller. The laser beam falls on the scanner mirror rotating at constant speed. The

laser beam reected from the scanner mirror is irradiated on the photosensitive drum.

Detecting a Failure in the Optical Assembly

When the laser scanner is placed in the following condition, the DC controller judges that a

failure occurred in the laser scanner unit and reports it to the main controller.

Laser failure

•

When the laser is turned on for a specied time at startup of the laser scanner unit, either

of the two laser beams does not reach the specied laser intensity.

Scanner motor startup failure

•

Even when a specied time elapses after startup of the laser scanner unit, the number of

rotations of the scanner motor does not reach a specied number of times.

Scanner motor rotation failure

•

When a specied BD interval cannot be detected during printing, it is judged that a BD error

occurred. When the BD interval cannot recover from the fault even after a specied time

elapsed after it was judged that a BD error occurred, it is considered that a scanner motor

rotation failure occurred.

Technical Reference > Laser Exposure System > Safety

Safety

The laser scanner unit of this machine does not have a mechanical laser shutter.

To secure safety, two interlock switches for +5VC are mounted. When the front door or right

door is opened, the interlock switch works and blocks power distribution to the laser scanner

unit.
