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.
