Principles of Operation
10- Electrical (PL10)
PWBA HKB PS
(PWBA LVPS)
The Low Voltage Power Supply Assy supplies AC power to the Heat Rod
and 5VDC, 3.3VDC, and 24VDC to the PWBA HKB26 MCU. The LVPS
Assy includes a safety interlock switch named the Switch Assy I/L Front.
When the Cover Assy Front is opened, the interlock opens the LVPS cir-
cuits, cutting all DC power.
PWBA HKB26 MCU
The Main Control Unit PWB, with input from sensors, switches, and the
printer controller, controls all printer operations. The PWBA HKB26 MCU
has five major functions.
1. Communicates with the printer controller.
2. Receives information from printer sensors and switches.
3. Controls the ROS Assy, Fuser Assy, and Drive components.
4. Controls the printing process.
5. Distributes DC power from the PWBA LVPS to other printer compo-
nents.
PWBA HVPS
The High Voltage Power Supply Assy supplies high voltage AC and DC to
the Fuser, BCR, BTR, Detack Saw, and Magnet Roll.
PWBA 5VDC
Converts 24VDC delivered from the PWBA LVPS to 5VDC to be supplied
to the PWB ESS.
PWBA Conn
Connective PWBA between the PWBA GHKB MCU and such the compo-
nents as Sensor Photo:Regi, Sensor Photo:Paper Set, Toner Sensor,
Solenoid Pick Up and Clutch Regi. This PWBA also has the interface port
to the PWBA ENV.
Switch Assy I/L Rear
The interlock switch which break the DC circuit of the Motor Assy Exit
when the Cover Rear opens.
Main Switch
Mounted on the printer frame. The Main Switch controls AC wall voltage
into the printer, and is used to switch the printer OFF and ON.
Power Cord
Connects the printer to an AC wall outlet. Power Cord types vary depend-
ing on the power rating of the printer (110/220VAC).
