[C]
Plate [A] aligns the leading edges of the pages of the document. When the
machine starts feeding the document, the mechanical clutch mechanism in
the ADF roller unit lifts up the pick-up roller [B] to feed the bottom sheet of the
document. Then, the feed roller [C] feeds the sheet into the scanner.
The separation rubber plate [D] prevents the feed roller from feeding more
than one sheet at a time.
