2. Pick-up and Separation
Plate [A] aligns the leading edges of the pages of the document. When the tx
motor starts, 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.
Because the line speed of the R1 roller [E] is 3 times faster than the feed and
pick-up rollers, the release mechanism [F] releases the feed and pick-up roll-
ers from the motor drive. This makes these rollers turn at the same speed as
the R1 roller, because they are still gripping the paper.
