Theory of Operation
2-41
Electrical
1. Engine Control Board:
Controls printing operation based on the
communication with the Image Processor Board and input from the sensors and
switches. Incorporates functions of the High-Voltage Power Supply.
Major Functions:
■
Communicates with the Image Processor Board
■
Receives information from the sensors and/or switches.
■
Controls the Laser Unit.
■
Supplies high-voltage to the Imaging Unit to perform charging,
development, primary transfer and secondary transfer
2. Image Processor Board:
Receives data from the workstation or host,
rasterizes the data and passes it on to the Engine Control Board. The
microprocessors on the Image Processor Board, generate the control signals used
by the Engine Control Board. The system NVRAM chip is also located on this
board and stores several printer parameters.
3. Motor Driver Board:
Controls motors through the signals received from the
Engine Control Board and sends information from the sensors and switches to
the Engine Control Board. Power from the low-voltage power supply is supplied
to the Engine Control Board through the Motor Driver Board. The interlock
switch is mounted on the Motor Driver Board.
