2.1 Basic Operation
2.1.1 Basic Operation (Finisher Unit)
0009-2533
The finisher is designed to deliver copies arriving from its host machine, and its modes of delivery include simple
stacking, job offset, and staple.
All operations involved in these modes are controlled by the finisher controller PCB, according to the appropriate
commands from the host machine.
In the case of the Saddle Finisher, copies from the host machine may be routed to the saddle stitcher unit.

Memo: The term job offset refers to shifting each sorting job, separating a single stack into several stacks.
2.1.2
Overview of the Electrical Circuitry (Finisher Unit)
0009-2534
The finisher's sequence of operation is controlled by the finisher controller PCB. The finisher controller PCB is a 16-
bit microprocessor (CPU), and is used for communication with the host machine (serial) in addition to controlling
the finisher's sequence of operations.
The finisher controller PCB responds to the various commands coming from the host machine through a serial
communications line to drive solenoids, motors, and other loads. In addition, it communicates the finisher's various
states (information on sensors and switches) to the host machine through a serial communications circuit.
In the case of the Saddle Finisher, the finisher controller PCB not only communicates with the saddle stitcher
controller PCB but also communicates the saddle stitcher unit's various states (information on sensors and switches)
to the host machine.
