5. ADF simplex scanning (The document moves over the immovable scanner module.)
(1) Set the document face up into the paper feed chute ASSY. 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 rubber 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 (paper feed roller
3 is CCD model only), and is passed over the scanner module so that the document
is scanned. Then, the document is ejected to the document cover (CCD model) or
Document eject tray (CIS model) by the eject roller.
