Image forming apparatus

摘要

An image forming apparatus provided with a sensor for detecting a sheet transport problem. When a sheet transport problem occurs before a sheet reaches an image forming section, the sheet is returned to a sheet feeding section, and when a transport problem occurs at or after the image forming section, the sheet is forwarded to a sheet receiving section. When the problem sheet is either returned to the feeding section or forwarded to the receiving section, the apparatus is set to an operational condition. When the problem sheet can be neither returned to the feeding section nor forwarded to the receiving section, further operation of the apparatus is inhibited.
