Abstract
An example scanner includes a tray, a document feeding member, a document feed error detection sensor, a reading member, and a processor. The processor, in a case where a document feed error is detected by the document feed error detection sensor, is to move the tray between a first position to feed a document, and a second position deviated from the first position, and control the document feeding member to perform a reverse feeding operation of feeding an erroneous document toward the tray. Based on performing the reverse feeding operation, the processor is to move the tray between the second position and the first position and control the document feeding member to perform a re-feeding operation of feeding the erroneous document to the reading member.
Claims20
A scanner comprising:
- a tray to receive a document and to ascend/descend between a first position to feed the document and a second position deviating from the first position;
- a reading member to read an image from the document;
- a document feeding member to feed the document to the reading member;
- a document feed error detection sensor to detect a document feed error caused by the document feeding member;
- and
- a processor, wherein the processor is to:
- based on detecting a document feed error by the document feed error detection sensor, move the tray between the first position to the second position and control the document feeding member to perform a reverse feeding operation of feeding an erroneous document toward the tray, and,
- based on performing the reverse feeding operation, move the tray between the second position and the first position and control the document feeding member to perform a re-feeding operation of feeding the erroneous document to the reading member.
A scanner comprising:
- a tray to receive a document and to ascend/descend between a first position to feed the document and a second position deviating from the first position;
- a reading member to read an image from the document;
- a document feeding member to pick up a document, and feed the document to the reading member comprising a pickup roller to ascend/descend between a third position to pick up a document, and a fourth position deviating from the third position;
- a document feed error detection sensor to detect a document feed error caused by the document feeding member;
- and
- a processor, wherein the processor is to:
- based on detecting a document feed error by the document feed error detection sensor, move the tray between the first position to the second position and control the document feeding member to perform a reverse feeding operation of feeding an erroneous document toward the tray;
- and
- control the document feeding member to perform a re-feeding operation of feeding the erroneous document to the reading member.
An apparatus, comprising:
- a tray to receive a document and to ascend/descend between a first position to feed the document and a second position deviating from the first position;
- a reading member to read an image from the document;
- a document feeding member to pick up a document, and feed the document to the reading member comprising a pickup roller to ascend/descend between a third position to pick up a document, and a fourth position deviating from the third position;
- a document feed error detection sensor to detect a document feed error caused by the document feeding member;
- and
- a processor, wherein the processor is to:
- based on detecting a document feed error by the document feed error detection sensor, move the tray between the first position to the second position and control the document feeding member to perform a reverse feeding operation of feeding an erroneous document toward the tray;
- and
- control the document feeding member to perform a re-feeding operation of feeding the erroneous document to the reading member, wherein the re-feeding operation includes moving the tray from the second position to the first position.
