INTRODUCTION

This Service Manual contains basic data and figures on the plain paper CLC1120/

1130/1150 needed to service the machine in the field. The copier is designed to enable

fully automated copying work, and may be configured with the following options:

RDF-E2

Stapler Sorter-F1

Film Projector-D1

Paper Deck-E1

For the RDF-E2, Stapler Sorter-F1, and Film Projector-D1, see their respective

Service Manuals for details. This Service Manual covers the copier itself, and consists of

the following chapters:

Chapter 1

General Description introduces the copier's features and specifications,

shows how to operate the printer unit, and explains how copies are made.

Chapter 2

Basic Operation provides outlines of the steps used to generate copies.

Chapter 3

Exposure System discusses the principles of operation used for the

mechanical/electrical operations of the copier's exposure system. It also

explains the timing at which the various units involved are operated, and

shows how they may be disassembled/assembled and adjusted.

Chapter 4

Image Processing System discusses the principles of operation used for

the mechanical/electrical operations of the copier's image processing

system. It also explains the timing at which the various units involved are

operated, and shows how they may be disassembled/assembled and

adjusted.

Chapter 5

Laser Exposure System discusses the principles of operation used for the

mechanical/electrical operations of the copier's laser exposure system. It

also explains the timing at which the various units involved are operated,

and shows how they may be disassembled/assembled and adjusted.

Chapter 6

Image Formation System discusses the principles of how images are

formed. It also explains the timing at which the various units involved in

image formation are operated, and shows how they may be disassembled/

assembled and adjusted.

Chapter 7

Pick-Up/Feeding System discusses the principles of how the printer unit

picks up and moves paper inside it. It also explains the timing at which the

various units involved are operated, and shows how they may be

disassembled/assembled and adjusted.

Chapter 8

Fixing System discusses the principles of how the printer unit fuses toner

images to paper. It also explains the timing at which the various units

involved are operated, and shows how they may be disassembled/

assembled and adjusted.

Chapter 9

Externals/Auxiliary Mechanisms shows the copier's external parts, and

explains the principles used for the copier's various control mechanisms in

view of the functions of electrical and mechanical units and in relation to

their timing of operation. It also shows how these units may be

disassembled/assembled and adjusted.

Chapter 10

Paper Deck discusses the principles of operation used for the series of

operations between pickup and delivery performed by the paper deck. It

also explains the timing at which the various units involved are operated,

and shows how they may be disassembled/assembled and adjusted.

Chapter 11

Installation introduces requirements for the site of installation, and shows

how the printer unit may be installed using step-by-step instructions.

Chapter 12

Maintenance and Servicing provides tables of periodically replaced parts

and consumables/durables and scheduled servicing charts.

Chapter 13

Troubleshooting provides tables of maintenance/inspection, standards/

adjustments, and problem identification (image fault/malfunction).

Appendix contains a general timing chart and general circuit diagrams.

The following rules apply throughout this Service Manual:

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 flipping on the power switch,

closing the front door, and closing the delivery unit door, which results in

supplying the machine with power.

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.
