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.

Use of this manual should be strictly supervised to avoid disclosure of confidential

information.

Explanation of Symbols

The following symbols are used throughout this Service Manual.

The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific 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 field. 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.

Points to Note About Turning Off the Main Power Switch

This machine has two switches related to power supply, the Power switch and the breaker.

Turning on the Power switch powers this machine.

The breaker detects an excess current and electric leakage to protect you against an electric shock.

MEMO:

Explain to the customer that the breaker must be checked once or twice a month and the result

must be recorded.
