<p>A sheet feeder includes a feed roller (12) for compelling a sheet from a stack of sheets (14) into a sheet path (16) and a pair of separation rollers (18, 20) rotating in the same direction for urging sheets along the sheet path (16). The separation rollers (18, 20) are selectively and separately disengaged from their power source with a motor (30) for the feed roller (12) to provide multiple checks for sheet multifeeds. At each check, extra sheets are returned to the stack of sheets (14).</p> |
