Board Block Diagram
This machine employs the GW (Grand Workware) architecture, which allows the printer to be expanded
by installing simple modular components (ROM DIMMs) in the controller board or installing optional
boards in the two controller board slots.
Here is a brief summary of the boards and their functions. For more details, refer to the Point-to-Point diagram
and list of components supplied with the printer.
BICU (Base Engine and Image Control Unit)
Controls all machine functions both directly and through other control boards.
LDB (Laser Diode Board)
Powers the laser diode. Output level is controlled to compensate for changes in temperature and humidity
to maintain constant laser write intensity.

are also built into this controller. The HDD unit is also attached to the controller board. The Controller Board
