2 Outline of the Manual

This Service Manual provides basic facts and figures needed to service the iR1600/

iR2000. Of the machine’s accessories, this manual covers the cassette unit and inner 2-way

tray; for other accessories including the ADF, see its own Service Manual.

In this manual, the 1-Cassette Unit-F1, 2-Cassette Unit-G1 and 3-Cassette Unit-H1 are

collectively called “cassette unit,” and the Inner 2-Way Tray-B1 is referred to as the inner 2-

way tray.

This Service Manual consists of the following chapters:

Chapter 1 Introduction: features, specifications, operation, system construc-

tion, routine maintenance by the user, safety, repro-

duction processes

Chapter 2 Basic Operation: basic operation, outline of electrical circuitry, basic

sequence

Chapter 3 Image Reading/

Processing System: principles of operation of the exposure system, prin-

ciples of operation of the image processing system,

timing of operation; disassembly/assembly and ad-

justment

Chapter 4 Laser Exposure System: principles of operation of the image formation sys-

tem, timing of operation; disassembly/assembly

Chapter 5 Image formation system: standards, adjustments, troubleshooting tables

Chapter 6 Pickup/Feeding System: principles of operation of the pickup/feeding sys-

tem, timing of operation; disassembly/assembly and

adjustment

Chapter 7 Fixing System: principles of operation of the fixing system, timing

of operation; disassembly/assembly and adjustment

Chapter 8 Externals and Auxiliary

Control System: principles of operation of the externals/auxiliary

control system, timing of operation; disassembly/

assembly and adjustment

Chapter 9 Cassette Unit: principles of operation of the pickup system; disas-

sembly/assembly and adjustments

Chapter 10 Inner 2-Way Tray: principles of operation; disassembly/assembly and

adjustment

Chapter 11 Installation: site requirements and installation procedure

Chapter 12 Maintenance and

Inspection: table of periodically replaced parts, table of

durables, scheduled servicing chart

Chapter 13 Troubleshooting: maintenance and inspection, standards/adjustment,

troubleshooting image faults/malfunctions; service

mode, self diagnosis

Chapter 14 Version up: version up

Appendix: general timing chart, general circuit diagram

INTRODUCTION

The descriptions are subject to change for product improvement, and major changes will

be communicated in the form of Service Information bulletins.

All service persons are expected to go through the contents of this Service Manual and

Service Information bulletins and have a good understanding of the machine, readying

themselves to promptly respond to the needs of the field (i.e., identifying and correcting

faults).

2002 CANON INC. 2001 2001 2001 2001 CANON iR1600/iR2000 REV.1 JAN. 2002

INTRODUCTION

The descriptions in this Service Manual are based on he following rules:

1. In each chapter, the uses of the function in question and its relationship to electrical and

mechanical systems are discussed and the timing of operation of its associated parts is

explained by means of outlines and diagrams.

In the diagrams, the symbol represents a mechanical path, while the symbol

with a name next to it indicates the flow of an electric signal.

The expression “turn on the power” means turning on the power switch, closing the

front door, and closing the delivery door so that the machine will be supplied with

power.

2. In circuit diagrams (digital), a signal whose level is High is expressed as being ‘1’,

while a single whose level is Low is expressed as being ‘0’; the level of voltage, how-

ever, varies from circuit to circuit.

The machine uses CPUs, whose internal mechanisms cannot be checked in the field,

and, therefore, are not explained. In addition, the machine’s PCBs are not intended for

repairs at the user’s and, therefore, are explained by means of block diagrams: two types

are used, i.e., between sensors and inputs of PCBs equipped with a control or drive func-

tion and between outputs equipped with a control or drive function and loads; in addi-

tion, functional block diagrams are used at times.

Changes made to the machine for product improvement are communicated in the form of

a Service Information bulletin as needed. All service persons are expected to go through all

service documentation including the bulletins and be equipped to respond to the needs of the

field (as by being able to identify possible causes of problems).

INTRODUCTION

Be sure to turn off the power switch and disconnect the power plug before starting disas-

sembly/assembly work; further, keep the following in mind:

1. If you turn off the main power switch while a printer function is in use, the data being

processed can be lost. Check to be sure that the online LED in the control panel is OFF

before operating the power switch.

2. Do not turn off the power switch while downloading is taking place; otherwise, the ma-

chine may fail to operate.

3. Remember that not all power will be removed in response to the opening of the front

cover as long as the power switch remains ON.

4. Be sure to use SHUT DOWN MENU to shut down the printer if the Hard Disk HD-65

(accessory) has been installed.
