Abstract
A printing apparatus that includes a holding unit configured to hold a roll sheet performs supplying the sheet by rotating the roll sheet held by the holding unit; nipping and conveying the supplied sheet; performing printing on the conveyed sheet; detecting occurrence of a print medium jam of the sheet; and, if the printing apparatus has detected a print medium jam of the sheet, performing a control process of supplying the sheet in a state in which the conveying is stopped.
Claims13
A printing apparatus comprising:
- a holding unit configured to hold a roll sheet;
- a supply unit configured to supply a sheet from the roll sheet by rotating the roll sheet held by the holding unit;
- a conveying unit configured to nip and convey the sheet supplied from the supply unit;
- a printing unit configured to perform printing on the sheet conveyed from the conveying unit;
- a cover unit configured to cover at least a part of the printing unit and not to cover the holding unit;
- a detecting unit configured to detect occurrence of a print medium jam of the sheet;
- a control unit configured to, in a case in which the detecting unit has detected a print medium jam of the sheet, control the supplying unit and the conveying unit in a control process to form a loop of the sheet between the holding unit and the conveying unit and outside of the cover unit;
- and
- a notifying unit configured to cause a notification device to provide a notification to a user to promote cutting the loop of the sheet after the control unit performs the control process and the loop of the sheet is formed.
A printing method of a printing apparatus comprising a holding unit configured to hold a roll sheet, a printing unit configured to perform printing on a sheet from the roll sheet, and a cover unit configured to cover at least a part of the printing unit and not to cover the holding unit, comprising:
- supplying a sheet from the roll sheet by a supply unit by rotating the roll sheet held by the holding unit;
- conveying the sheet by a conveying unit nipping the sheet supplied from the supply unit;
- printing, by the printing unit, on the sheet conveyed from the conveying unit;
- detecting occurrence of a print medium jam of the sheet by a detecting unit;
- controlling, in a case in which a print medium jam of the sheet has been detected in the detecting, the supply unit so as to form a loop of the sheet between the holding unit and the conveying unit and outside of the cover unit;
- and
- causing a notification to a user to promote cutting the loop of the sheet after the controlling.
