Abstract
A disabled state in which sheets cannot be discharged at a discharge unit while printing is detected. Upon detecting the disabled state, printing is continued at a printing unit, and a sheet printed upon is evacuated to a storage unit without cutting into a plurality of cut sheets at a cutter unit. After the disabled state is resolved, the sheet which has been evacuated to the storage unit is sent to the cutter unit so as to be cut into the cut sheets, and discharged at the discharge unit.
Claims13
An apparatus capable of duplex printing, comprising:
- a sheet feeding unit configured to feed a sheet, wherein the sheet is continuous;
- a print unit configured to perform printing on the sheet fed from the sheet feeding unit;
- a cutter unit capable of cutting the sheet, which has been printed by the print unit, into a plurality of cut sheets;
- a discharge unit configured to discharge the cut sheets;
- a reverse unit configured to temporarily store the sheet for reversing and sheet feeding the reversed sheet to the printing unit again;
- a detecting unit configured to detect a disabled state in which sheets cannot be discharged at the discharge unit;
- and
- a control unit,
- wherein upon the disabled state being detected by the detecting unit while printing, the control unit controls to continue printing at the printing unit, and evacuate the sheet printed to the reverse unit for temporarily storing, without cutting into the cut sheets, and
- wherein after the disabled state is resolved, the control unit controls to send the sheet, which has been evacuated to the reverse unit, to the cutter unit so as to be cut into the cut sheets, and to discharge the cut sheets at the discharge unit.
An apparatus comprising:
- a sheet feeding unit configured to feed a sheet, wherein the sheet is continuous;
- a print unit configured to perform printing on the sheet fed from the sheet feeding unit;
- a cutter unit capable of cutting the sheet, which has been printed by the print unit, into a plurality of cut sheets;
- a discharge unit configured to discharge the cut sheets cut by the cutter unit;
- a storage unit configured to temporarily store the sheet printed at the print unit and feed the stored sheet to the printing unit;
- a detecting unit configured to detect a disabled state in which sheets cannot be discharged at the discharge unit;
- and
- a control unit;
- wherein upon the disabled state being detected by the detecting unit while printing, the control unit controls to continue printing at the printing unit, and evacuate the sheet printed to the storage unit for temporarily storing, without cutting into the cut sheets, and
- wherein after the disabled state is resolved, the control unit controls to send the sheet, which has been evacuated to the storage unit, to the cutter unit so as to be cut into the cut sheets, and to discharge the cut sheets at the discharge unit.
A method for controlling a printing apparatus including a sheet feeding unit configured to feed a continuous sheet, a print unit configured to perform printing on the sheet fed from the sheet feeding unit, a cutter unit capable of cutting a sheet which has been printed by the print unit into a plurality of cut sheets, a discharge unit configured to discharge the cut sheets, and a storage unit configured to temporarily store the sheet printed at the printing unit and feed the stored sheets to the printing unit, the method comprising:
- detecting of a disabled state in which sheets cannot be discharged at the discharge unit;
- continuing printing upon the disabled state being detected at the printing unit and evacuating the sheet printed upon to the storage unit without cutting into the cut sheets;
- sending the sheet which has been evacuated to the storage unit to the cutter unit so as to be cut into the cut sheets after the disabled state is resolved;
- and
- discharging the cut sheets at the discharge unit.
