2 Outline of the Manual

This Service Manual provides basic facts and figures needed to service the SmartBase PC1200 Series/iR1200 Series products in the field, and it consists of the following chapters:

Chapter 1	Product Outline:	specifications, names of parts, safety and warnings
Chapter 2 Using the Machine:		control panel, user mode, service mode
Chapter 3	Installation:	site requirements, installation procedure, work for reloca-
		tion
Chapter 4	Operation:	mechanical system by function, principles of operation of
		electrical systems
Chapter 5	Mechanical System:	mechanical construction, disassembly/assembly
Chapter 6	Maintenance and Inspection: periodically replaced parts, durables (life), basic servicing
		chart, cleaning
Chapter 7	Troubleshooting:	standards/adjustments, troubleshooting image faults,
		troubleshooting malfunctions
Appendix:		general timing chart, general circuit diagrams

CANON SmartBase PC1200s/iR1200s REV. 0 DEC. 2001

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 cover, and closing the delivery cover 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, however, 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 function and between outputs equipped with a control or drive function and loads; in addition, 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).
