Abstract: The sheet processing system includes: an image forming unit forming an image on a sheet; a sheet stack unit that lowers along a moving route, as more sheets are stacked on the sheet stack unit, the sheets each having an image formed by the image forming unit and being transported through a first route; a processing unit provided in a housing, and applying processing to a sheet having an image formed by the image forming unit, the sheet being transported through a second route; a cover member provided so that a part of the housing is openable, partially reaching a position in the moving route when the part is opened, and allowing a user to operate the processing unit by opening the part; and a moving unit moving the sheet stack unit to a position where the sheet stack unit does not interfere with the cover member, upon abnormal transportation.
