Image Processing Assembly and Main Board
The Main Board receives image data from the host computer, converts it to a
bitmap image, and then transfers the image to the Laser Scan Unit (LSU).
The Main Board combines the Image Processor and Engine Control
func
tions. It contains a 32 bit RISC processor and comes with a standard
memory capacity of 64 Mbytes of RAM and 4 Mbytes of flash memory. The
board provides one expansion slot that allows available memory to be
expanded up to 512 Mbytes with two 256Mbyte RAM DIMM.
