CHAPTER 2 OPERATIONS
I . BASIC CONSTRUCTION
A. Electrical Circuitry
The machine's electrical mechanisms are controlled by the ADF controller PCB. The CPU on
the ADF controller PCB interprets input signals from the machine's sensors and the host copier, and
generates signals to drive the motors, solenoids, and other DC loads.

B. Communication with the Copier
The machine communicates using IPC communication 2, which enables communication at a
higher speed than the existing IPC methods.
