The Machine Control Unit (MCU) Board controls the printing process based
on the communication with the printer Image Processor Board and
information from the Sensors or Switches. Major functions include:
1.
Communicates with the Image Processor Board.
2.
Receives information from the Sensors or Switches.
3.
Controls the Motors in the Main Drive and PH Drive Assembly.
4.
Distributes low-voltage DC power generated from the LVPS to each
component.
5.
Controls the Laser Unit.
Note
When replacing an MCU Board, ensure to transfer the NVRAM from the
old MCU Board to the new MCU Board.
