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 prod-
uct improvement or other purposes, and major changes will be communicated in the form

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 (small-
sized 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 offset function delivers the first 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 sta-
pling at front, diagonal stapling at rear, 2-point stapling).
5. Uses a buffer roller.
●The use of a buffer roller enables the finisher 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 op-
eration (up to 50 copies of small-size paper or up to 30 copies of large-size paper; both
of 80 g/m2).
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 arrival of
a fax on tray 2/3.
