Theory of Operation
SFP Image Processor Board
The Image Processor (IP) Board is connected to the MCU Board, and controls the
printer, including diagnostic, interface, and image processing. The primary
function of the IP Board is to receive and process host data from the USB or
Ethernet port. The host data is buffered, stored, and sent to the MCU Board in a
rasterized format.
When installing a new IP Board in the printer, transfer both NVRAM and RAM
DIMM memory from the old board to the new board.
