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:
1.
2.
3.
4.
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 copiers 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 copiers 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 copiers 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 copiers 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.

System Configuration
The CLC1120/1130/1150 may be configured as follows to make up a system (the shaded areas
indicate accessories):
RDF-E2
Feeds a large number of originals
automatically for continuous
copying. Accepts double-sided
originals.
Editor-F1
Enables selecting areas and
colors using a point pen.
Stapler Sorter-F1
Sorts or groups copies.
Staples sorted copies.
The figures above represents the CLC1150; however, the CLC1120/1130 may be configure in
the same way.
CLC1120: 2-cassette model
CLC1130: 3-cassette model
CLC1150: 2-cassette model with a duplexing unit.
