Control of most electrical components in this printer is by a microcomputer on the DC controller PCB.
This microcomputer receives information from sensors, the Test switch, and the external device. Using a built-in
program, this microcomputer directs the operation of AC loads (via the AC driver), the laser, the scanner (via the
scanner driver), the main motor (via the main motor driver), the high-voltage power supply, DC loads, and the
display unit.
