2.1.5. Pick-up and Feed (ADF)

[B]
[A]
When the ADF motor starts, the mechanical clutch [A] moves the pick-up
roller [B] down to the document. Then, the machine feeds the top page of the
document. After the last page is scanned, the ADF motor reverses briefly to
move the pick-up roller back to the standby position.

2.1.6. Separation Mechanism (ADF)

The feed roller [A] and the separation roller [B] prevent more than one sheet
of paper from feeding into the scanner at once.
When the feed roller feeds a sheet of paper, both the feed and the separation
rollers rotate in the feed-in direction. However, if two or more sheets are be-
tween these rollers, the separation roller rotates in the feed-out direction to
prevent the lower sheet from being fed into the scanner.
