Engine H/W Specifications
Main Board
The Engine Board and the Controller Board are in one united board, and it is consisted of CPU
part and print part in functional aspect. The CPU is functioned as the bus control, I/O handling,
drivers, and PC interface. The main board sends the Current Image of Video data to the LSU and
manages the conduct of Electrophotography for printing. It is consisted of the circuits of the motor
(paper feed, pass) driving, clutch driving, pre-transfer lamp driving, current driving,
and fan driving. The signals from the paper feed jam sensor and paper empty sensor are directly
inputted to the main board.
