Abstract
In the event that occurrence of a jam has been detected during conveyance of a sheet, the sheet is cut at a cutter unit, and a user is prompted to perform manual jam restoration processing according to the location where the jam has occurred. If the jam has occurred upstream from the cutter unit, the cut sheets left downstream from the cutter unit are discharged as completed articles.
Claims14
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 configured to cut the sheet printed at the print unit;
- a detecting unit configured to detect a jam occurred when the sheet being conveyed;
- and
- a control unit configured to control such that, in the event that the detecting unit detects the jam, the cutter unit cuts a sheet, and also prompts a user to perform manual jam restoration processing according to the location where the jam has occurred.

An apparatus for 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;
- a cutter unit configured to cut the sheet printed at the print unit;
- a detecting unit configured to detect a jam occurred when the sheet being conveyed;
- a reverse unit configured to reverse the sheet printed at the print unit for the duplex printing;
- and
- a control unit;
- wherein the control unit controls so that, in the duplex printing, the printing unit performs printing a plurality of images on a first surface of the sheet fed from the sheet feeding unit, the printed sheet is reversed by the reverse unit to feed the reversed sheet to the printing unit, the printing unit performs printing a plurality of images on a second surface that is a back of the first surface of the sheet fed from the reverse unit, and the cutter unit cuts the sheet into a plurality of cut sheets,
- and wherein, in the event that the detecting unit detects the jam at least during printing on the first surface, the cutter unit cuts the sheet, and the control unit causes to display a location where the jam has occurred on a display to prompt a user to perform jam restoration processing.
6 more elements
A method for jam restoration with a printing apparatus, comprising:
- feeding a sheet from a sheet feeding unit, wherein the sheet is continuous;
- printing a plurality of images sequentially on the sheet fed from the sheet feeding unit;
- cutting the printed sheet into cut sheets each having the image by a cutter unit;
- discharging the cut sheets to a discharge unit;
- detecting a jam occurred when the sheet being conveyed;
- and
- in the event that the jam has occurred upstream from the cutter unit, stopping the printing and discharging the cut sheets to the discharge unit.
