PRINTING APPARATUS AND CONTROL METHOD THEREOF

摘要

A printing apparatus according to one aspect of this invention automatically discharges, of sheets remaining on a conveyance path when a sheet being conveyed jams, dischargeable sheets to one of a plurality of sheet retraction units. At this time, the printing apparatus detects the stacked state of sheets discharged to the sheet retraction unit. When the printing apparatus detects that the sheet retraction unit has become a predetermined state, it changes the discharge destination of sheets to be conveyed to the sheet retraction unit, thereby controlling not to further discharge a sheet to that sheet retraction unit. According to this control, when retracting sheets remaining on the conveyance path upon occurrence of a jam in the printing apparatus, occurrence of a new jam can be prevented.

主权项

1. A printing apparatus comprising:
a plurality of sheet retraction units each configured to be used as a discharge destination of a sheet remaining on a conveyance path of the sheet when a sheet jams on the conveyance path; a discharge control unit configured to control to, when a sheet being conveyed through the conveyance path jams, discharge the sheet remaining on the conveyance path to a sheet retraction unit; a detection unit configured to detect a stacked state of sheets on the sheet retraction unit; and a change unit configured to, when the detection unit detects that the stacked state of sheets on the sheet retraction unit have become a predetermined state while the discharge control unit discharges the sheet remaining on the conveyance path, change the discharge destination of the sheet remaining on the conveyance path from the sheet retraction unit to another sheet retraction unit.
