This Service Manual contains basic data and figures for the Finisher (AR-F11)/Saddle

Finisher (AR-F12) 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

“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 dia-
grams 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 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.
