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 sen-
sors 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:
Host machine DC
