[4] 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
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

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).
