Printing apparatus, method and storage medium for conveying sheets intermittently to printhead while conveyed sheets partially overlap

To shorten the time to be taken to start executing a process to handle conveyance trouble of a print medium after the occurrence of the conveyance trouble, a printing apparatus of the present invention, upon sensing of conveyance trouble by a sensing unit during a printing operation, stops the conveyance of the print medium in the conveyance trouble and any print medium located upstream of it, and moves a printing head from a first position at which the printing head performs printing on a print medium to a second position to which the printing head is retreated from the first position, in parallel with a discharge operation for conveying, to a discharge unit, any print medium located downstream of the print medium in the conveyance trouble.

Printing apparatus

In a printing apparatus, the ends of print media fed continuously can be prevented from colliding with each other. The printing apparatus includes a printing unit configured to perform a print operation, a detecting unit configured to detect a conveyance abnormality, a conveying unit configured to convey a preceding print medium and a succeeding print medium, a conveying path having a first area including a curved portion at which a conveying direction of the print medium is curved and a second area upstream of the first area, and an opening unit capable of opening the first area of the conveying path. In a case in which a leading edge of the succeeding print medium is located in the second area at the time of the detecting unit detecting conveyance abnormality of the preceding print medium, the conveying unit conveys the succeeding print medium so that the leading edge of the succeeding print medium reaches the first area.

A printing apparatus can be downsized while degradation in the print quality can be suppressed. To perform skew correction on a second print medium on which printing is to be performed subsequent to a first print medium, a first conveying unit disposed upstream of the printing position where the printing unit performs printing on the print medium is stopped. Then, driving and stopping of third conveying unit disposed downstream of a second conveying unit is controlled, depending on whether the first print medium after printing has already passed by the second conveying unit when the first conveying unit is stopped, the second conveying unit being driven by the same driving source as that for the first conveying unit and being disposed downstream of the printing position.
