Outline of Electrical Circuitry
The finisher’s operation sequences are controlled by the finisher controller PCB, which is a 32-
bit CPU. The finisher controller PCB is also used to control communication (serial) with the copier.
The CPU on the finisher controller PCB is equipped with a built-in ROM used to store
operation sequence programs.
The finisher controller PCB drives motors in response to various commands coming from the
copier through serial communication lines. On the other hand, it communicates the state of each
sensor and switch to the copier in serial mode of communication.
The ICs on the finisher controller PCB have the following functions:
■
Q1 (CPU; w/ built-in flash ROM)
Controls sequence.
Stores sequence programs.
■
Q2 (communication IC)
Communicates with the copier (IPC II).
■
Q8 (regulator IC)
Generates 5 V used to drive sensors and logic system.
