11.3.2.1.2. Outline of the Electrical Circuitry
The sequence of finisher operations is controlled by the Finisher Controller PCB. The Finisher Controller
PCB is a 16-bit microprocessor (CPU), and is also used for combination with the Host Machine (serial).
The Finisher Controller PCB Drive Motors and other loads in response to the various commands from the
Host Machine. It also communicates such data as on the states of various sensors and switches to the Host
Machine by way of the serial communication line.
The ICs mounted to the Finisher Controller PCB have the following functions:
• IC13 (CPU)
Controls sequence of operations.
• IC12 (EEP-ROM)
Backs up adjustment settings.
• IC6 (EP-ROM)
Stores sequence programs.
• IC11 (communication IC)
Communicates with the host machine.
• IC1 (regulator IC)
Generates 5 V.
Fig. 2-001 shows the flow of signals between finisher and options controller.
