The finisher consists of four blocks: a stack tray, stapler, intermediate process tray, and feeder blocks.
The following illustration shows locations of these four blocks and the finisher controller PCB.

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.
