CHAPTER 2 OUTLINE OF OPERATION
1.2 Outline of the Electrical Circuitry
The sequence of finisher operations is controlled by the finisher controller PCB. The fin-
isher 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 com-
mands 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:
