5. ADF simplex scanning (The document moves over the immovable CCD unit.)
(1) Set the document face up into the document chute. When the machine starts
simplex 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 ejected
to the document cover LGL by the eject roller.
