  • Publication number: 20220324666
    Abstract: A printing apparatus, in a case of performing double-sided printing on a plurality of sheets, performs an overlap reversing operation by controlling a first sheet to stay in a reversing path to position at least a trailing edge of the first sheet relative to a second direction in a conveying path when conveying the first sheet to the reversing path after completion of a printing operation on a first surface of the first sheet, and controls the reversing roller to convey the first sheet and a second sheet fed by a feed roller next to the first sheet, in a state in which the first sheet staying in the reversing path and a leading edge of the second sheet relative to the second direction overlap each other, after completion of the printing operation on a first surface of the second sheet.

  • Patent number: 10065438
    Abstract: A printing apparatus includes a feeding unit configured to feed a printing sheet, a conveyance unit configured to convey the printing sheet fed by the feeding unit, a printing unit configured to print the printing sheet conveyed by the conveyance unit, and a control unit configured to control conveyance of a preceding sheet and a succeeding sheet fed after the preceding sheet. The control unit makes a leading edge of the succeeding sheet overlap the preceding sheet and the control unit decides an overlapping amount of the preceding sheet and the succeeding sheet such that the overlapping amount, in a case when an ink amount discharged on at least one of the preceding sheet and the succeeding sheet is greater than a threshold, is less than the overlapping amount in a case when the ink amount is less than the threshold.
