The main control board CPU manages the scanner, operation panel, and printer
engine to control the entire copier system.
The scanner IPU board CPU controls the scanner motor and image data
processing. Both the main control board and the scanner IPU board have flash
memory so that their programs can be replaced using a flash ROM card.
The main control board controls the printer controller through the CIVIC interface
(this is Ricoh's proprietary parallel colour video interface).
