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
The saddle unit built into the finisher is used to fold a stack of sheets
coming from the finisher unit in half for delivery.
All these operations are controlled by various commands sent by the
host machine in addition to the commands from the finisher controller
host machine in addition to the commands from the finisher controller
PCB.
The puncher unit (option) is designed for installation to the pickup
assembly of the finisher, and is used to punch holes in sheets coming
assembly of the finisher, and is used to punch holes in sheets coming
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.
Fig.F02-101-01
NOTE:The position of delivery is shifted to the front/rear for each stack 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 microprocessor
(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 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.

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
