The main controller handles the video controller, engine controller and scan controller.
The main controller receives print data from the host through the network or USB port, and it receives copy data from the
Scan Controller. It takes this information and generates printable video bitmap data. It controls all modules required to
print, that is, LSU, HVPS, FAN, Fuser, etc.
The main controller communicates with the drive system and other devices through UART(Universal Asynchronous
Receiver Transmitter). It communicates with the toner cartridge and drum/developer unit through I2C to check their life.
The main controller adopted Dure Core CPU 1GHZ, DDR3 1GB memory, Flash NAND 128MB, 320GB SATA HDD to
control the engine driving, video signal processing, interface, etc. successfully.
