Abstract
A sheet discharger includes: an accommodator configured to accommodate sheets; a conveyor configured to convey and discharge a sheet to the accommodator; a detector configured to detect whether a jam of a sheet has occurred in the accommodator and a state of the jam; and a controller configured to control the 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.
Claims6
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.

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;
- 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 stackers configured to accommodate sheets,
- the sheet discharge conveyor is configured to convey a sheet conveyed via a printer and is capable of switching a sheet discharge destination between the stackers, and
- the processor is configured to control the sheet discharge conveyor to switch a stacker as the sheet discharge destination for a subsequent sheet discharged after a sheet being discharged to the stacker as the sheet discharge destination at a time of occurrence of the jam in the state where sheet discharge of the jammed sheet is possible, depending on whether the subsequent sheet has been properly printed by the printer.

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.
