The printer unit controller PCB generates the following DC voltages using the 13 VDC supplied by the printer unit:
- 24 VDC (for motor drive)
- 13 VDC (for LED array)
- 5 VDC (for sensor drive)
- 3.3 VDC (for IC drive/for CCD drive)
24 VDC power is used to drive the motors, while 13 VDC power is used to turn on the LED array for illumination of originals.
