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.
