General Precautions for Installation/Servicing/Maintenance for the Finisher
AR-FN11/FN12, Hole punch unit AR-PN3, Inserter AR-CF1
The installation and service should be done by a qualified service technician.
1. When installing the Finisher AR-FN11/FN12, Hole punch unit AR-PN3, Inserter ARCF1 to the Plain Paper Copier, be sure to follow the instructions described in the “Unpacking/Set-Up Procedure for the AR-FN11/FN12/AR-PN3/AR-CF1” booklet which
comes with each unit of the AR-FN11/FN12/AR-PN3/AR-CF1.
2. The AR-FN11/FN12, AR-PN3, AR-CF1 should be installed by an authorized/qualified
person.
3. Before starting installation, servicing or maintenance work, be sure to turn off and unplug the copier first.
4. When selecting the installation site, avoid placing the AR-FN11/FN12/AR-CF1 and
copier on different levels or inclined floors.
5. When servicing or maintaining the AR-FN11/FN12/AR-PN3/AR-CF1, be careful about
the rotating or operation sections such as gears, pulleys, sprockets, cams, belts, etc.
6. When parts are disassembled, reassembly is the reverse of disassembly unless otherwise noted in this manual or other related materials. Be careful not to reassemble small
parts such as screws, washers, pins, E-rings, toothed washers to the wrong places.
7. Basically, the machine should not be operated with any parts removed or disassembled.
8. Delicate parts for preventing safety hazard problems (such as breakers, thermofuses,
fuses, door switches, sensors, etc. if any) should be handled/installed/adjusted correctly.
9. Use suitable measuring instruments and tools.
10. During servicing or maintenance work, be sure to check the serial No. plate and other
cautionary labels (if any) to see if they are clean and firmly fixed. If not, take appropriate
actions.
11. The PC board must be stored in an anti-electrostatic bag and handled carefully using
a wristband, because the ICs on it may be damaged due to static electricity. Before
using the wrist band, pull out the power cord plug of the copier and make sure that
there is no uninsulated charged objects in the vicinity.
12. For the recovery and disposal of used AR-FN11/FN12/AR-PN3/AR-CF1s, consumable parts, packing materials, used batteries, and RAM-ICs including lithium batteries,
it is recommended that the relevant local regulations/rules.
13. After completing installation, servicing and maintenance of the AR-FN11/FN12/ARPN3/AR-CF1, return the AR-FN11/FN12/AR-PN3/AR-CF1 to its original state, and
check operation.

the timing at which these systems are operated.
Chapter 5“Inserter (option) Unit Basic Operation” discusses the principles of operation
used for the inserter units mechanical and electrical systems. It also explains
the timing at which these systems are operated.
Chapter 6“Mechanical System” discusses how the finisher is constructed mechanically,
and shows how it may be disassembled/assembled and adjusted.
Chapter 7“Maintenance and Inspection” provides tables of periodically replaced parts
and consumables and durables, together with a scheduled servicing chart.
Chapter 8“Troubleshooting” shows how to troubleshoot possible faults and gives electri-
cal parts arrangement diagrams, LED/check pin diagrams by PCB, and self
diagnosis tables.
“Appendix” contains diagrams showing tables of signals, overall circuit diagrams and tables of solvents/oils.
Descriptions regarding installation are not mentioned in this Service Manual as the
Finisher (AR-F11)/Saddle Finisher (AR-F12)’s packing boxes contain Installation Procedures.
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 280 mm in height in its two bins (small-size
paper: equivalent to 2000 sheets)/140 mm in height (large-size paper: equivalent to 1000
sheets)
2.Has high paper transportation performance
• The finisher is capable of handling papers between 60 and 256 gm/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 AR-FN12)
• 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 60 and 256 gm/m². It cannot handle special paper, postcards and transparencies.)
8.Insert function (option)
• Enable the use of special type of paper and printed paper in addition to the staple sorting or
the hole punching mode (Available when the optional staple sorting and the hole punching
mode units are installed.) This paper is not run through fuser (heat).
