Pick-Up And Feed (Adf); Separation Mechanism (Adf) - Ricoh C226 Service Manual

ORIGINAL FEED SECTION

1.1.5 Pick-up and Feed (ADF)

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

1.1.6 Separation Mechanism (ADF)

[A]
[B]
The feed roller [A] and the separation roller [B] prevent more than one sheet
of paper from being fed 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
between the rollers, the separation roller will rotate in the feed-out direction to
prevent the lower sheet from being fed into the scanner.
