The Main Controller controls all modules required to print, that is, LSU, HVPS, SMPS, FAN, Fuser, etc.
The Main Controller receives print data from the host through network or USB Port. It takes this information
and generates printable video bitmap data. Engine and Video Controller are not separated.
