[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.

*: The position of delivery is shifted to the front/rear for each stack
to assist sorting.
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.
