2.4.2 Main PBA
The CLP-620/670 series system controller consists of a main controller and a engine controller in one-board.
The main controller uses a ARMS core chip as a main processors, which are dedicated for printing several
internal operating blocks through system programs stored in Flash Memory. The engine controller has an
engine control SoC, which includes motor drivers, PWM drivers, LSU drivers, sensors, high-voltage drivers,
and other driving units for mechanical parts.
