SM 7-111 D0CA/D0C9/D0C8/D0CB
It also has an interface with the BiCU (PCB1), and controls scanner input and output
signals according to CPU commands.
LD control circuit which drives the laser diode with a universal driver.
Controls the engine, as well as the sensors, motors and solenoids of main machine.
Controls the fax program.
Controls the control panel.
Generates high-voltage power required for image creation.
The High-Voltage Power Supply unit consists of two units: PCB23 is for transfer and
PCB22 is for charging/developing.
Generates DC power from the main AC power supply, and supplies it to each control
circuit. Contains an A/C drive circuit for controlling the fusing lamp.
Detects the voltage of the main AC supply.
Controls motors, sensors, and solenoids in the ADF.
