2.2.4.1 Main PBA

The Engine and the Printer Controller function are housed into one Main Board called Main PBA. 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 electrophotography for printing. The CPU on Main PBA

manages the circuits for the motors: paper feed, paper path, clutches, pre- transfer lamp, current control to

driver components, and fan driving. The signals from the paper feed jam sensor and paper empty sensor are

directly inputted to the main board.
