Function
VBCU: 1) Engine sequence control (all sensors, motors,
fusing temperature monitoring circuits), 2) Scanning
control, 3) Exposure control, 3) Image processing control,
4) GW controller I/F, 5) Peripheral timing control.
The I/O control board controls 1) Input/output ports for all
sensors, motor, solenoids, 2) drivers, 3) high voltage power
supply for PWM, and 4) analog input signals.
Contains and controls the laser diodes that fire a laser beam
at the rotating polygon mirror. Splits the laser beam in the
sub-scan direction to improve 1200-dpi resolution of Black,
Yellow, Cyan and Magenta.
