SL-M3015 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, FAN, Fuser, 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 adopts the 600 MHz CPU, on board DDR3 memory (128MB) to perform printing jobs successfully.
