MAIN FUNCTIONS
PWBA MCU
PWBA MCU performs communication with the printer controller, and controls the
parts to perform printing operations.
LV/HVPS
LV/HVPS supplies +24 VDC, + 5VDC and +3.3 VDC to each of the parts from
the AC power supply, and supplies high voltage to the parts for transferring and
discharging.
PWBA HVPS
PWBA HVPS supplies high voltage to IBT Cleaner, 2nd BTR, and Cleaning
Sheet.
PWBA FUSER CONT
PWBA FUSER CONT performs ON/OFF control of Fuser Lamp, and turns the
AC power to be supplied to the printer ON/OFF by the switch located on PWBA.
PWB ASSY ROT
PWB ASSY ROT creates the pulse for the motors according to input signal from
the PWBA MCU and supplies the pulse signal to the motors.
