  • Sheet feeder, control method of sheet feeder, and storage medium
    Patent number: 11591175
    Abstract: In a case where feeding of a subsequent sheet by a feed roller is started after the trailing edge of a preceding sheet is detected by a post-registration sensor, a control unit of a sheet feeder controls the feed roller to rotate at a first feeding speed, and in a case where the leading edge of the subsequent sheet has passed through a nip position between the feed roller and a separation roller, the control unit controls the feed roller to rotate at a second feeding speed.
    Type: Grant
