Electrical Module
1 LVPS Assembly The Low Voltage Power Supply Assembly supplies AC power to the
Heater Rod and 24VDC to the printer logic circuits. The LVPS
Assembly includes the safety interlock switch and the Main Power
Switch. When the Front Transport Assembly is open, the interlock
opens the LVPS circuits, cutting all power except to the Fan circuit.
The Main Power Switch controls AC wall power into the printer, and is
used to turn the printer ON and OFF.
2 HVPS Assembly The High Voltage Power Supply Assembly supplies power to the BCR,
BTR, and Magnet Roll.
3 MCU PWB The Main Control Unit PWB, with input from sensors, switches, and the
printer controller, controls all printer operations. The MCU PWB has six
major functions:
1. Communicate with the printer controller
2. Receive information from printer sensors and switches
3. Control the ROS, Fuser, and Drive Assemblies
4. Control the Console
5. Control the printing
6. Distribute power from the LVPS to other components
4 Fan Ventilates the printer interior to prevent overheating.
5 ESS (Controller)
(not shown)
The ESS is above and parallel to the MCU and HVPS PWBs.
