The main board handles the video control, engine control and scan control.
The main board receives the print data from the host through the network or USB port, and it receives the copy data from the
scan control part. It takes this information and generates printable video bitmap data. It controls all modules required to
print, that is, LSU, HVPS, fan, fuser, scan function, LCD display, touch screen.
