Abstract
A sheet feeding device includes a sheet loader, a sheet feeder, a misfeeding detector, a memory, and circuitry. The sheet loader is configured to load a sheet of a sheet bundle. The sheet feeder is configured to feed a sheet from the sheet bundle loaded on the sheet loader. The misfeeding detector is configured to detect a misfeeding of the sheet. The memory is configured to store sheet feed information on sheet feeding. The circuitry is configured to change a sheet feed setting based on the sheet feed information stored in the memory and perform a retry sheet feeding at a detection of the misfeeding by the misfeeding detector.
Claims20
A sheet feeding device, comprising:
- a sheet loader configured to load a sheet of a sheet bundle;
- a sheet feeder configured to feed the sheet from the sheet bundle loaded on the sheet loader;
- a misfeeding detector configured to detect a misfeeding of the sheet;
- a memory configured to store sheet feed information on sheet feeding, wherein the sheet feed information includes sheet information of the sheet;
- and
- circuitry configured to change a sheet feed setting based on the sheet feed information stored in the memory and perform a retry sheet feeding in response to detecting the misfeeding by the misfeeding detector.
A sheet feeding device, comprising:
- a sheet loader configured to load a sheet of a sheet bundle;
- a sheet feeder configured to feed the sheet from the sheet bundle loaded on the sheet loader;
- a misfeeding detector configured to detect a misfeeding of the sheet;
- a memory configured to store sheet feed information on sheet feeding;
- and
- circuitry configured to change a sheet feed setting based on the sheet feed information stored in the memory and perform a retry sheet feeding in response to detecting the misfeeding by the misfeeding detector,
- wherein the circuitry is further configured to:
- estimate a cause of the misfeeding based on the sheet feed information stored in the memory and the sheet feed information that has resulted in the misfeeding prior to the retry sheet feeding;
- change the sheet feed setting based on the estimated cause of the misfeeding;
- and
- perform the retry sheet feeding.
A sheet feeding device, comprising:
- a sheet loader configured to load a sheet of a sheet bundle;
- a sheet feeder configured to feed the sheet from the sheet bundle loaded on the sheet loader;
- a misfeeding detector configured to detect a misfeeding of the sheet;
- a memory configured to store sheet feed information on sheet feeding;
- circuitry configured to change a sheet feed setting based on the sheet feed information stored in the memory and perform a retry sheet feeding in response to detecting the misfeeding by the misfeeding detector;
- and
- a drive state detector configured to detect a drive state of the sheet feeder,
- wherein the sheet feed information includes the drive state of the sheet feeder detected by the drive state detector.
