when a jam has occurred in a sheet of during conveyance, the control unit sets order information of dischargeable sheets among unusable sheets remaining inside the apparatus after occurrence of the jam based on whether there is an unusable sheet on which image formation has been completed in the image forming unit, and discharges the unusable sheet to an outside of the apparatus through the conveyance path based on the set order information.
2. The image forming apparatus according to claim 1, wherein the control unit determines whether there is an unusable sheet on which image formation has been completed in the image forming unit based on whether there is an unusable sheet that has arrived at an exit of the image forming unit.
3. The image forming apparatus according to claim 1, wherein the conveyance path includes branching and merging.
4. The image forming apparatus according to claim 1, wherein, when a jam of a sheet has occurred in one conveyance path that has branched, the control unit performs the discharge of the unusable sheet existing on the conveyance path before branching through a conveyance path branching into another.
5. The image forming apparatus according to claim 1, wherein the order information is included in data of the job as one piece of attribute information of each sheet.
6. The image forming apparatus according to claim 1, wherein the control unit adds information indicating that a sheet is unusable to attribute information corresponding to the unusable sheet.
7. The image forming apparatus according to claim 1, wherein the control unit discharges the unusable sheet to a sheet discharge destination different from a sheet discharge destination of a normal sheet.
8. The image forming apparatus according to claim 1, wherein, when the jam has occurred, the control unit performs the discharge of sheets giving priority to an order of a conveyance path to be used by a normal sheet among sheet-conveyable conveyance paths.
9. The image forming apparatus according to claim 1, wherein the control unit sets the order information according to an arrangement order of sheets arranged along an order of sheet-conveyable conveyance paths.
10. The image forming apparatus according to claim 1, wherein the control unit performs the discharge of sheets without changing an order as a result of order information determination in the setting of the order information.
11. The image forming apparatus according to claim 1, wherein the control unit changes an order and performs the discharge of sheets as a result of order information determination in the setting of the order information.
12. The image forming apparatus according to claim 1, wherein, when discharging an unusable sheet, the control unit sets the sheet not to be subjected to post-processing.
13. The image forming apparatus according to claim 1, wherein, when discharging an unusable sheet, the control unit sets size information in attribute information of the sheet to a maximum size with which conveyance setting is possible.
14. The image forming apparatus according to claim 1, wherein, when discharging an unusable sheet, the control unit sets basis weight information in attribute information of the sheet to a maximum basis weight with which conveyance setting is possible.
15. The image forming apparatus according to claim 1, wherein, when the jam has occurred, the control unit stops conveyance of the sheet, and discharges the unusable sheet after removal of the jammed sheet.
16. An image forming system comprising:
the image forming apparatus according to claim 1; and
an external apparatus.
17. The image forming system according to claim 16, wherein the external apparatus includes a part of the sheet conveyance unit.
18. A method of forming an image conveyed through a conveyance path based on a job, the method comprising:
when a jam has occurred in a sheet of during conveyance, setting order information of dischargeable sheets among unusable sheets remaining inside an apparatus after occurrence of the jam based on whether there is an unusable sheet on which image formation has been completed in an image forming unit, and discharging the unusable sheet to an outside of the apparatus through the conveyance path based on the set order information.
19. The method of forming an image according to claim 18, wherein whether there is an unusable sheet on which image formation has been completed in the image forming unit is determined based on whether there is an unusable sheet that has arrived at an exit of the image forming unit.
20. The method of forming an image according to claim 18, wherein, when a jam of a sheet has occurred in one conveyance path that has branched, the discharge of the unusable sheet existing on the conveyance path before branching is performed through a conveyance path branching into another.
