[5] OPERATIONAL DESCRIPTION
1. Basic operations
A. Specifications
The finisher serves to deliver sheets coming from its host machine.
The mode of delivery may be non-sort stack, job offset *, or staple
delivery.
The saddle unit built into the finisher is used to fold a stack of
sheets coming from the finisher unit in half for delivery.
The punch unit (option) is designed for installation to the pickup
assembly of the finisher, and is used to punch holes in sheets com-
ing from the host machine.
The above operations are controlled with various commands from
the finisher controller PCB as well as the commands from the
punch controller PCB.

to assist sorting.
B. Outline of the Electrical Circuitry
The sequence of finisher operations is controlled by the finisher
controller PCB. The finisher controller PCB is a 16-bit microproces-
sor (CPU), and is also used for combination with the host machine
(serial).
The finisher controller PCB drive motors and other loads in
response to the various commands from the host machine. It also
communicates such data as on the states of various sensors and
switches to the host machine by way of the serial communication
line.
The ICs mounted to the finisher controller PCB have the following
functions:
• IC13 (CPU): Controls sequence of operations.
• IC12 (EEP-ROM): Backs up adjustment settings.
• IC6: Stores sequence programs.
• IC11 (expansion port): I/O port
The flow of signals between finisher and options controller is shown
as below.

2. Feed/Drive System
A. Outline
The machine performs the following in response to the commands
coming from its host machine on the sheets arriving from the host
machine for delivery: simple stacking, job offset, and stapling or
folding (in two).
If a punch unit (option) is installed, the sheets are pouched and
delivered to the delivery tray.
Sheets may be delivered in either of five ways (including one for
the punch unit):

If a punch unit (option) is installed, the sheets are pouched and
delivered to the delivery tray.
Sheets may be delivered in either of five ways (including one for
the punch unit):
(1) Normal Delivery
a. Simple Stacking
The machine pulls in the sheet once to the processing tray and
then delivers it to the delivery tray.
The machine pulls in the sheet once to the processing tray and
then delivers it to the delivery tray.
b. Job Offset
The machine pulls the sheet once to the processing tray. It then
moves the sheet to the front or the rear using the aligning plate.
When it has deposited a specific number of sheets, it delivers them
in the form of a aligning plane. When the number of sheets stacked
on the processing tray reaches a specified value, the sheets are
delivered in a form of a stack.

c. Stapling
The machine stacks sheets coming from its host machine on the
processing tray. When the number of sheets stacked on the pro-
cessing tray reaches a specified value, the finisher staples them
delivers the stapled stack to the delivery tray.
