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.

Abstract: An image scanning apparatus includes an image sensor to scan a paper, a paper feeding apparatus to pick up a loaded paper and move the picked-up paper to a paper feeding path, a sensor to output a predetermined signal value when the paper is sensed at a predetermined position in the paper feeding path, and a processor to control the paper feeding apparatus to move the paper depending on a scan command. The processor confirms a length of the paper based on a signal sensed in the sensor, and controls the paper feeding apparatus to pick up the loaded paper based on the confirmed length.

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, based on a document feed error being detected by the document feed error detection sensor, is to perform a reverse feeding operation of feeding an erroneous document toward the tray by using the document feeding member, and based on performing the reverse feeding operation, perform a re-feeding operation of feeding the erroneous document to the reading member by using the document feeding member.

Abstract: A scanner includes a lower unit and an upper unit. The lower unit includes a first document table on which a first document is to be placed. The upper unit includes a second document table on which a second document is to be loaded and a document feed path through which the second document is to be picked up from the second document table fed, the upper unit being coupled to the lower unit to pivot between a closed position in which the first document table is covered and an open position in which the first document table is exposed. The upper unit further includes a reading unit to read an image from the first document and the second document by performing flatbed scanning on the first document and document feed scanning on the second document.

Abstract: An image scanning apparatus includes an image sensor to scan a manuscript, a transfer apparatus to pick up the manuscript and move the manuscript to a manuscript transfer path, and a loading apparatus to load the manuscript scanned by the image sensor. The loading apparatus includes a discharge tray to hold a discharged manuscript and a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript.
