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 Quad Core CPU 1.5GHZ, DDR3 4GB(old model)/6GB(new model(IR UI) memory, Micro
SD 4GB(old model)/eMMC 4GB(new model(IR UI)), 320GB SATA HDD to control the engine driving, video signal
processing, interface, etc. successfully.
A MICOM at the main controller controls the fuser lamp on/off and system power according to an optimized energy-saving
algorithm for optimal efficiency. It also communicates with the OPE Controller through the USB 2.0 protocol to display
the system information on LCD.
