General Precautions for Installation/Servicing/Maintenance for the Finisher

AR-F15/F16, Hole punch unit AR-PN4

The installation and service should be done by a qualified service technician.

When installing the Finisher AR-F15/F16, Hole punch unit AR-PN4 to the Plain Paper Copier,

be sure to follow the instructions described in the “Unpacking/Set-Up Procedure for the

AR-F15/F16/AR-PN4” booklet which comes with each unit of the AR-F15/F16/AR-PN4.

2. The AR-F15/F16, AR-PN4 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-F15/F16 and copier on dif-

ferent levels or inclined floors.

5. When servicing or maintaining the AR-F15/F16/AR-PN4, be careful about the rotating

or operation sections such as gears, pulleys, sprockets, cams, belts, etc.

When parts are disassembled, reassembly is the reverse of disassembly unless other-

wise 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.

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 appropri-

ate 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-F15/F16/AR-PN4s, consumable parts, pack-

ing materials, used batteries, and RAM-ICs including lithium batteries, it is recom-

mended that the relevant local regulations/rules.

13. After completing installation, servicing and maintenance of the AR-F15/F16/AR-PN4,

return the AR-F15/F16/AR-PN4 to its original state, and check operation.

14. When you move the finisher, do not move it in the direction of the arrow as shown in

the figure below otherwise it might fall down.

INTRODUCTION

This Service Manual contains basic data and figures for the Finisher (AR-F15)/Saddle

Finisher (AR-F16) 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 stitch 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, and self

diagnosis tables.

“Appendix”contains diagrams showing tables of signals, overall circuit dia-

grams and tables of solvents/oils.

Descriptions regarding installation are not mentioned in this Service Manual as the

Finisher (AR-F15)/Saddle Finisher (AR-F16)’s packing boxes contain Installation Proce-

dures.

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

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.

I. FEATURES

1. Accommodates large quantities of sheets

• Normally, the finisher holds a stack of sheets 250 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 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 host machine even during stapling or offset operation.

6. Has a saddle stitch function (Saddle Finisher AR-F16)

• 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 can-

not 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).
