The operation sequence of the finisher is controlled by the finisher controller PCB.
The finisher controller PCB incorporates a 16-bit CPU to perform sequence control (and
serial communication with the host machine).
The CPU on the finisher controller PCB incorporates a ROM that stores an operation
sequence program.
The finisher controller PCB drives motors in response to the commands sent from the host
machine via a serial communication line.
The finisher controller PCB also sends information about various sensors and switches to
the host machine via the serial communication line.
