SBU (Sensor Board Unit)
The SBU does the following:
•
Takes the analog signals from the CCD and converts them to digital.
•
Sends serial data to the BICU.
•
Sends signals from the main CPU to the SIOB, to control the scanner
components.
SIOB (Scanner I/O Board)
This board controls all the sensors in the scanner unit and the scanner motor. The
CPU controls this board through the interfaces on the SBU and the BICU.
LDB (Laser Diode Drive Board)
This board contains the driver for the laser diodes.
DRB (Drive Board)
This board contains the circuits for the stepper motors that drive the printer engine,
and distributes electrical power to all the other PCBs.
