Control Panel
The Control Panel is the user interface for display of printer status and operation of
the printer.
Controller Board
The Controller Board consists of the CPU and printer control functions. The CPU
functions as the bus control, I/O handling, drivers, and PC interface. The Controller
Board sends the current image video data to the Laser Unit and manages the
electrophotographic printing process. Circuits on the Controller Board drive the
Motor (paper feed), Clutch, Heat Lamp, and Fan.
The signal from the Out Bin Empty Sensor is input directly to the Controller Board.
Note
Each printer model has a unique Controller Board. The following illustration
shows the 3160N Controller Board.
