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.
