INTRODUCTION

This Service Manual contains basic data and figures for the Finisher-C1/Saddle Fin-

isher-C2 needed to service the machine in the field. Chapter 1 ‘General Description’ introduces the finisher’s features, specifications, and

names of parts, and shows how to operate the sorter.

Chapter 2 ‘Finisher Unit Basic Operation’ discusses the principles of operation used for

the finisher mechanical and electrical systems. It also explains the timing at which these systems are operated.

Chapter 3 ‘Saddle Stitcher Unit Basic Operation’ discusses the principles of operation

used for the saddle stitcher unit’s mechanical and electrical systems. It also explains the timing at which these systems are operated.

Chapter 4 ‘Mechanical System’ discusses how the finisher is constructed mechanically,

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

Chapter 5 ‘Maintenance and Inspection’ provides tables of periodically replaced parts

and consumables and durables, together with a scheduled ser vicing chart.

Chapter 6 ‘Troubleshooting’ provides tables of maintenance/inspection, standards/ad-

justments, and problem identification (image fault/malfunction). ‘Appendix’ contains diagrams showing tables of signals, tables of solvents/

oils, and a general timing chart.

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.

CHAPTER 1 GENERAL DESCRIPTION

I. FEATURES

1. Accommodates large quantities of sheets

●

Normally, the finisher holds a stack of sheets 220.6 mm in height in its three bins (smallsized paper of 80 g/m2; no stapling).

2. Has high paper transportation performance.

●

The finisher is capable of handling papers between 50 and 157 g/m2.

3. Offers a job offset function.

●

The finisher’ s job of fset function deli v ers the f irst or the last sheet of each job by displacing it to the front, enabling sorting of copies on the tray.

4. Offers four types of auto stapling.

●

The finisher offers a choice of four stapling modes (1-point stapling at rear, diagonal stapling at front, diagonal stapling at rear, 2-point stapling).

5. Uses a buffer roller.

●

The use of a buffer roller enables the f inisher to accept copies without interruption from the copier even during stapling or offset operation (small-size paper only).

6. Offers an interrupt delivery function.

●

Installation of the interrupt delivery tray will enable an interruption of an ongoing operation (up to 50 copies of small-size paper or up to 30 copies of large-size paper; both of 80 g/m

2

).

7. Has a saddle stitch function (Saddle Finisher-C2).

●

The finisher can staple along the center of paper and fold it in two (up to 15 sheets).

8. Offers an incoming fax indicator (option).

●

When installed, the incoming fax indicator lamp (LED) will turn on to indicate the arriv al of a fax on tray 2/3.
