duplex scanning. The ADF motor is rotated clockwise, the pick-up roller draws the
document, and the separation roller and separation pad send a sheet of the
document to the ADF one by one from the top page of the stacked documents.

module so that the document is scanned. In duplex scanning, the document is sent
to the paper feed roller 3 by the switch back flap A, because the switch back flap A
goes up. Then the document is sent for the specified distance by the switch back
roller, and the switch back roller is turned counter so that the document is drawn
again.
