11.1.2.1.2. Outline of Electrical Circuitry
The Finisher's sequence of operation is controlled by the Finisher Controller PCB. The Finisher Controller
PCB is a 16-bit microprocessor (CPU), and is used for communication with the Copier (serial) in addition to
controlling the finisher's sequence of operations.
The Finisher Controller PCB responds to the various commands coming from the Copier through a serial
communications line to drive solenoids, motors, and other components. In addition, it communicates the
Finisher's various states (information on sensors and switches) to the Copier through a serial
communications circuit.
The Finisher Controller PCB not only communicates with the Saddle Stitch Controller PCB but also
communicates the Saddle Stitch Unit's various states (information on sensors and switches) to the Copier.
The ICS used on the Finisher Controller PCB are designed for the following:
•Q1 (CPU)
Controls sequence of operations.
• Q2 (EP-ROM)
Backs up adjustment values.
•Q7
Contains sequence programs.
• Q8 / Q89 (RAM)
Backs up initial setting data.
• Q4 (communications IC)
Communicates with the copier and the saddle stitch unit.
• Q14 (regulator IC)
Generates 5V.
Flow of signals between the finisher and the options controller:
