Phaser 6130 Color Laser Printer Service Manual
Machine Control Unit Board
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 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, be sure to transfer the NVRAM from the
old MCU Board to the new MCU Board.
High-Voltage Power Supply (HVPS)
The HVPS provides high-voltage power to the components in the Transfer Belt
and Imaging Unit to perform charging, development, and primary transfer of
the print process to the BCR, BTR, and Developer.
Electrically Erasable Programmable Read-Only Memory (EEPROM) Board
The EEPROM Board stores the printer unique information.
Control Panel
The Control Panel displays the printer status and operates the printer.
