Claim 3:
4. A The 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; 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 stacker includes a first stacker configured to accommodate sheets and a second stacker different from the first stacker and configured to accommodate sheets,
the sheet discharge conveyor includes a common route, a branch route connected to a part of the common route, a first stack route extending from a downstream end of the common route in a sheet conveyance direction to the first stacker, and a second stack route extending from the downstream end of the common route to the second stacker,
the jam of a sheet in the stacker includes a jam in which a sheet being discharged to the first stacker is retained at an exit of the first stack route, and
upon detection by the detector of the jam in a state where sheet discharge of a retained sheet which is a sheet retained at the exit of the first stack route is not possible and upon a next sheet after the retained sheet having entered the first stack route at a time of detection of the jam in the state, the processor is configured to control the sheet discharge conveyor to convey the next sheet from a downstream side in the sheet conveyance direction into the branch route, then convey the next sheet out of the branch route to the second stacker via the second stack route, and convey a sheet subsequent to the next sheet to the second stacker.
