Beschreibung
Zusammenfassung:	A sheet feeder may include a feed roller for compelling a sheet from a stack of sheets into a sheet path and a pair of separation rollers rotating in the same direction for urging sheets along the sheet path. The separation rollers may be selectively and separately disengaged from their motive source in coordination with operation of a motor for the feed roller to provide multiple checks for sheet multifeeds. At each check, extra sheets are returned to the stack of sheets. The separation rollers may each include plural annular spaced-apart sheet contact surfaces that are interleaved with the contact surfaces of the other roller.
