Printing apparatus and control method therefor

摘要

A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from a stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit which determines whether to convey the succeeding sheet to a position facing the printing unit while keeping an overlap state between the preceding sheet and the succeeding sheet. The determination unit determines whether the printing sheet is suitable for overlap conveyance, and if the determination unit determines that the printing sheet is unsuitable for overlap conveyance, the conveyance control unit conveys the succeeding sheet while the succeeding sheet does not overlap the preceding sheet.

主权项

1. A printing apparatus comprising:
a feeding roller configured to feed a printing sheet; a conveyance roller configured to convey the printing sheet fed by the feeding roller; a printing unit configured to print the printing sheet conveyed by the conveyance roller; a contact member arranged between the feeding roller and the conveyance roller, wherein a state of the contact member is changeable by swinging when the contact member contacts the printing sheet; a conveyance control unit configured to control conveyance of printing sheets so as to form an overlap state where a trailing edge of a preceding sheet as a printing sheet precedingly fed and a leading edge of a succeeding sheet as a printing sheet succeedingly fed overlap each other between the feeding roller and the conveyance roller; and a determination unit configured to determine whether to convey the succeeding sheet to a position facing the printing unit while keeping the overlap state or to convey the succeeding sheet to the position after canceling the overlap state based on a state change of the contact member.
