Ref. 2-8
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 back in again.
Fig. Ref2-8
(3) The drawn back 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 back of the
document is scanned. The document is sent to the switch back roller ASSY again.
