This Service Manual contains basic data and figures on the reader unit of the color
copier needed for servicing in the field.
The machine consists of the following system units:
1. Reader unit
2. Editor
3. Original holder
For the printer unit, duplexing unit, R cassette, and PS/PCL board, refer to their
respective Service Manuals. This manual covers the reader unit, editor, and original hold-
er, and consists of the following chapters:
Chapter 1 General Description introduces the machine's features and specifications
and shows how to operate the machine.
Chapter 2 Basic Operation provides outlines of the machine's various mechanical
workings.
Chapter 3 Exposure System discusses the principles of operation used for the
machine's lens drive unit and scanner drive unit. It also explains the timing at which these
drive units are operated, and shows how they may be disassembled/assembled and
adjusted.
Chapter 4 Image Processing System discusses the CCD mechanism and the princi-
ples of how analog/digital images are processed. It also explains the timing at which the
various units may be disassembled/assembled and adjusted.
Chapter 5 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 6 Installation introduces requirements for the site of installation, and shows
how the machine may be installed using step-by-step instructions.
Chapter 7 Maintenance and Servicing provides tables of periodically replaced parts
and consumables/durables and scheduled servicing charts.
Chapter 8 Troubleshooting provides tables of maintenance/inspection, standards/adjust-

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