Abstract
A medium feeding apparatus includes a media tray, a feed roller to sequentially feed a plurality of media placed on the media tray, a separation roller located facing the feed roller, and circuitry. The circuitry detects a leading end position of each of a plurality of media in a nip between the feed roller and the separation roller, determines a distance between a leading end position of a preceding medium, which is of the plurality of media in the nip, and a leading end position of a medium following the preceding medium, and sets a characteristic value of the separation roller based on the distance.
Claims12
A medium feeding apparatus, comprising:
- a media tray;
- a feed roller to sequentially feed a plurality of media placed on the media tray;
- a separation roller located facing the feed roller;
- and
- circuitry configured to:
- detect a leading end position of each of a plurality of media in a nip between the feed roller and the separation roller;
- determine a distance between a leading end position of a preceding medium, which is one of the plurality of media in the nip, and a leading end position of a medium following the preceding medium;
- and
- set a characteristic value of the separation roller based on the distance.
A medium feeding method, comprising:
- sequentially feeding a plurality of media placed on a media tray by a feed roller;
- detecting a leading end position of each of a plurality of media in a nip between the feed roller and a separation roller located facing the feed roller;
- determining a distance between a leading end position of a preceding medium, which is one of the plurality of media in the nip, and a leading end position of a medium following the preceding medium;
- and
- setting a characteristic value based on the distance.
A non-transitory recording medium storing a plurality of instructions which, when executed by one or more processors of a medium feeding apparatus, causes the one or more processors to perform a method, the method comprising:
- sequentially feeding a plurality of media placed on a media tray by a feed roller;
- detecting a leading end position of each of a plurality of media in a nip between the feed roller and a separation roller located facing the feed roller;
- determining a distance between a leading end position of a preceding medium, which is one of the plurality of media in the nip, and a leading end position of a medium following the preceding medium;
- and
- setting a characteristic value of the separation roller based on the distance.
