Electrical Control Unit
Overview
The electrical control block governs all the control mechanisms of the machine, i.e., stacking
block, transport block, intermediary tray block, and saddle stitcher block.
The electrical control block consists of 2 entities: finisher controller PCB and saddle stitcher
controller PCB.

Finisher Controller PCB
The finisher controller PCB drives the various loads (motors, solenoids) of the machine in
response to the commands from the host machine (copier), and indicates the states of the
sensors and switches to the host machine.
It also serves to control the punch unit and the saddle finisher controller PCB.
