Abstract
Official abstract text for this publication.
A sheet feeder control method for controlling a sheet feeder of an image forming apparatus includes feeding a sheet through a sheet feed path exposable to the exterior of the sheet feeder, detecting the feeding of the sheet at at least a first position on the sheet feed path, discharging the fed sheet to the exterior of the sheet feeder, detecting the discharge of the sheet at a second position downstream of the first position in a sheet feeding direction, detecting a sheet jam during the feeding and discharging of the sheet, and if the jammed sheet is detected at the second position but not at the first position, cancelling a malfunction state due to the sheet jam when the sheet stops being detected at the second position, irrespective of whether the sheet feed path is covered or exposed.
