INTRODUCTION
This Service Manual contains the basic data and figures for the Finisher AR-FN8/Saddle
Finisher AR-FN9 needed to service the machine in the field.
This manual comprises the following chapters:
Chapter 1“General Description” introduces the finisher’s features, specifications, and
names of parts, and shows how to operate the finisher.
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 Finisher 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“Puncher (option) Unit Basic Operation” discusses the principles of operation
used for the puncher unit’s mechanical and electrical systems. It also explains
the timing at which these systems are operated.
Chapter 5“Mechanical System” discusses how the finisher is constructed mechanically,
and shows how it may be disassembled/assembled and adjusted.
Chapter 6“Maintenance and Inspection” provides tables of periodically replaced parts
and consumables and durables, together with a scheduled servicing chart.
Chapter 7“Troubleshooting” shows how to troubleshoot possible faults and gives electri-
cal parts arrangement diagrams, LED/check pin diagrams by PCB.
“Appendix” contains diagrams showing tables of signals, overall circuit diagrams and tables of solvents/oils.
Descriptions of installation are not mentioned in this Service Manual as the Finisher/
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.

• Normally, the finisher holds a stack of sheets 147 mm in height in its two bins (small-size
paper: equivalent to 1000 sheets)/74 mm in height (large-size paper: equivalent to 500 sheets)
2.Has high paper transportation performance.
• The finisher is capable of handling paper between 60 and 200 g/m2.
3.Offers a job offset function.
• The finisher has a job offset function for sorting non-stapled stacks of copies.
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 finisher to accept copies without interruption from the
host machine even during stapling or offset operation.
6.Has a saddle stitch function (Saddle Finisher).
• The finisher can staple along the center of paper and fold it in two (up to 15 sheets).
7.Offers a punch function (option).
• The use of the puncher unit enables the finisher to punch sheets for binders before they are
output. (The puncher unit is capable of handling papers between 64 and 200 g/m2. It cannot
handle special paper, postcards and transparencies.)
