The components of this finisher are organized into 3 major blocks; feed unit, processing tray unit and stack tray unit.

Overview of Electrical Circuitry

This machine's sequence of the operation is controlled by the finisher controller PCB.
The finisher controller PCB has the CPU(IC1), and the controller also controls the communication with the host machine in addition
to controlling this machine's operation sequence.
The CPU(IC1) on the finisher controller PCB contains a flash ROM used to store the operating sequence program.
The finisher controller PCB uses the UFDI communication line to receive various commands from its host to drive the motors. It
also uses serial communications to send information on the sensors and switches to its host.
The setting value of the service mode in the finisher is memorized in CPU(IC1).
