Claim 0:
1. A sheet discharger comprising:
a stacker configured to accommodate sheets;
a sheet discharge conveyor configured to convey and discharge a sheet to the stacker;
a detector configured to detect whether a jam of a sheet has occurred in the stacker and a state of the jam, wherein the detector includes a sheet retention discharge sensor configured to determine the time at which a rear end of a sheet is discharged from a sheet discharge route to the stacker; and
a processor configured to control the sheet discharge conveyor to continue sheet discharge upon detection by the detector of the jam in a state where sheet discharge of a jammed sheet is possible, wherein the processor
determines that a jam has occurred, and
controls the sheet discharge conveyor to continue sheet discharge upon detection by the sheet retention discharge sensor of the jam in which sheet discharge of the jammed sheet is possible,
in response to determining that the time at which the sheet retention discharge sensor detects discharge of the rear end of the sheet from the sheet discharge route is later than a predetermined time.
