2.2.3 Engine H/W Specifications
2.2.3.1 Dell 5330dn (PCL) 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, O/O handling, drivers, and PC interface.
The main board sends the Current Image by Video data to the LSU and manages the conduct of Electro
photo graphy 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.
