Power Switch
An actuator and linkage is used to activate the Power Switch located on the Low-
Voltage Power Supply.
High-Voltage Power Supply Board (HVPS)
Supplies high-voltage to the Transfer Roller and Imaging Unit.
Low-Voltage Power Supply Board (LVPS)
Supplies AC power from the power source to the Fuser heater. Generates and
supplies stable low-voltage DC power (+3.3 VDC, +5 VDC, and +24 VDC) to be
used for the logic and other circuits within the printer. The LVPS includes the
LVPS Board with attached Power Switch, the AC Harness, and the box
enclosure.
Engine Control Board
Controls printing operation based on the communication with the Image
Processor Board and input from the sensors and switches.
Major Functions:
Communicates with the Image Processor Board
Receives information from the sensors and/or switches.
Generates the video for the laser based on information from the Image
Processor Board.
Controls high-voltage sent to the Imaging Unit to perform charging,
development, primary and secondary transfer.
Distributes the low-voltage DC power from the Low-Voltage Power Supply.
Controls the motor in the Main Drive Assembly, Developer Drive Assembly,
Fuser Drive Assembly, Duplex Motor Assembly and the Toner Cartridge
Holder.
