M202x series has a system board of integrated engine controller and video controller.
The engine controller controls all modules required to print, that is, LSU, HVPS/SMPS, Fuser, Motor etc. It communicates
with the video control block inside CPU for printing. And it has the interface for all video sync signal to print out
the video data.
The video controller receives print data from the host through network or USB Port. It takes this information and generates
printable video bitmap data.
The main board is adopted 600 MHz A1500 CPU (only Europe) or A1000 CPU that is integrated with engine controller,
video controller, SDRAM, Flash ROM. It uses SDRAM and Flash ROM inside the ASIC chip.
