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. RDF-E2

2. Stapler Sorter-F1

3. Film Projector-D1

4. 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:

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:

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, signal name accompanies the symbol

represents the path of mechanical drive where a

, 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.

2. 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.

System Configuration

The CLC1120/1130/1150 may be configured as follows to make up a system (the shaded areas

indicate accessories):

CLC Film Projector-D1

Projects 35mm negative or

RDF-E2

Feeds a large number of originals automatically for continuous

positive film, large-size negative film, or transparencies for making

color copies. 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.

CLC Paper Deck-E1

Accommodates as many as 2500 sheets of copy paper (A4/B5/LTR).

CLC Buffer Path Unit 1

Limits curling of copied paper.

Control Card-V

Enables control of copying work by group.

The figures above represents the CLC1150; however, the CLC1120/1130 may be configure in

the same way.

CHAPTER 1 GENERAL DESCRIPTION

I. FEATURES

1. High Image Quality

The copier uses micro-diameter toner and a limited amount of silicone oil, ensuring a thin layer of toner on transparencies. It allows changing the hues of magenta toner and, together with the use of a direct mapping method, enables a wider range of color reproduction.

2. High Productivity

The copier turns out as many as 11 copies per minute in full color, or 42 mono-color copies. It takes as little as 18.4 sec to generate each first copy.

3. High Stability

The copier uses a new method to control the concentration of toner, promising stable production of high-quality copies.

4. Varied Transfer Materials

The copier allows the use of paper from as thin as 64 g/m

to as thick as 209 g/m2.

5. Large Source of Paper

The addition of accessories will equip the copier with a paper source ready to provide as many as 4400 sheets.

3 Cassettes (standard): 550 sheets x 3 cassettes (CLC1130 only; for CLC1120/1150,

550 sheets x 2 cassettes) Multifeeder: 250 sheets CLC Paper Deck-E1*: 2500 sheets *Accessory.
