This Service Manual contains basic data and figures on the color printer needed to

service the machine in the field.

This machine consists of the following system units:

Reader unit

Editor

Original holder

Printer unit

Duplexing unit

R cassette

PS/PCL board*

* Remains disabled when the printer unit is used in a copier mode.

For the reader unit, duplexing unit, R cassette, and PS/PCL board, refer to their

respective Service Manuals. This manual covers the printer unit, duplexing unit, and R

cassette, and consists of the following chapters:

Chapter 1 General Description introduces the machine's features and specifications,

shows how to operate it, and explains how copies are made.

Chapter 2 Basic Operation provides outlines of the machine's various mechanical

workings.

Chapter 3 Laser Exposure System discusses the principles of operation used for the

mechanical/electrical operations of the machine's laser system. It also explains the tim-

ing at which the various units involved are operated, and shows how they may be disas-

sembled/assembled and adjusted.

Chapter 4 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 5 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 adjust-

ed.

Chapter 6 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 oper-

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

Chapter 7 Externals/Auxiliary Mechanisms shows the machine's external parts, and

explains the principles used for the machine'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 8 Installation introduces requirements for the site of installation, and shows

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

Chapter 9 Maintenance and Servicing provides tables of periodically replaced parts

and consumables/durables and scheduled servicing charts.

INTRODUCTION

Chapter

Troubleshooting

provides

tables

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:

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.

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 cir-

cuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD sig-

nal goes on when `0'.

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.

2. 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 prod-

uct 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.
