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 or fax, Scanner. It takes this information
and generates printable video bitmap data. Engine and Video controller are not separated.
The main controller adopts the CHORUS4N(1GHz) CPU, A1500(600MHz), DIMM PBA on DDR3 memory to perform
printing jobs successfully.
The OPE Controller displays the status of the system using 4.3inch TFT LCD in response to user actions or the Main
controller.
The HVPS supplies high voltage for developing process. High Voltage controlled by PWM signal from CPU.
SMPS makes +5V and +24V DC from 220V or 110 AC.
