ADF duplex scanning (The document moves over the immovable CCD unit.)
(1) Set the document face up into the document chute. When the machine starts 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.
(2) The document is passed through the paper feed rollers 1, 2 and 3, and is passed over the CCD
unit so that the document is scanned. Then, the document is sent for the specified distance by
the switch back roller ASSY, and the switch back roller is turned counter so that the document
is drawn again.

(3) The drawn document is attached on the flap B and sent to the paper feed rollers 2 and 3. At
this time, the opposite side of the document is faced-up so that the backside of the document is
scanned. The document is sent to the switch back roller ASSY again.
