A printing apparatus includes a printing unit, and first, second, and third conveyance paths. The printing unit performs printing at a printing position on a print medium conveyed in a conveyance direction. The first conveyance path causes the print medium to pass through the printing position of the printing unit. The second conveyance path reverses obverse and reverse surfaces of the print medium, and the third conveyance path reverses obverse and reverse surfaces of the print medium. The second conveyance path branches from the first conveyance path at a first branching point on a downstream side of the printing position in the conveyance direction and merges into the first conveyance path on an upstream side of the printing position. The third conveyance path branches from a second branching point on the second conveyance path and merges into the first conveyance path on the upstream side of the printing position.

Printing apparatus

A printing apparatus includes a supply unit, a supply path, first and second conveyance paths, a printing unit, and an inversion roller. The first conveyance path conveys, to a first direction, a print medium. The printing unit prints an image on the two surface of the print medium. The inversion roller inverts a conveyance direction of the print medium and conveys the print medium in a second direction. The second conveyance path conveys the print medium conveyed in the second direction to the first conveyance path while inverting the print medium. When performing printing on both sides of print media, the print media are convey such that a first print medium supplied from the second conveyance path and a second print medium supplied from the supply path overlap in the first conveyance path.

Printing apparatus, control method thereof, and storage medium to reduce a size of a printing apparatus without a deterioration in productivity of double-sided printing

A recording apparatus to record an image on a sheet includes a roller pair and a switching unit. The roller pair sandwiches the sheet between the roller pair to convey the sheet. The switching unit switches between a first state in which the roller pair sandwiches the sheet and a second state in which rollers of the roller pair are separated from each other. The switching unit includes a first movable member that is moved in a first direction so that the first state is switched to the second state, and includes a second movable member that is moved in a second direction different from the first direction so that the first state is switched to the second state.

Recording apparatus

A printing apparatus, in which it is possible to easily clean the surface of a feeding roller and a separation roller by using a damp cloth or the like, includes a feeding roller that feeds a printing medium; a separation roller capable of selectively taking a state where a separating force that separates a plurality of printing media conveyed by the feeding roller one by one has occurred and a state where the separating force has not occurred at a position at which the separation roller is in pressure contact with the feeding roller; and a control unit configured to perform control to bring about a standby state where transmission of a driving force between a driving source of the feeding roller and the feeding roller is shut off in a state where the separating force has not occurred and the feeding roller and the separation roller abut each other.

Printing apparatus, control method of printing apparatus, and storage medium

A printing apparatus includes a feeding roller configured to feed a printing sheet stacked on a stacking unit, 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 conveyance control unit configured to control conveyance of printing sheets so that the trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and the leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit configured to determine 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.

Printing apparatus, control method therefor and storage medium

A printing apparatus includes a first feeding roller, a feeding motor configured to drive the first feeding roller, a second feeding roller, a conveyance roller, a conveyance motor configured to drive the conveyance roller, a printing unit configured to print the printing sheet, a detection sensor configured to detect the leading edge of the printing sheet, and a control unit configured to, when the printing unit performs a printing operation on a preceding sheet, drive the feeding motor in synchronization with the conveyance motor before the detection sensor detects the leading edge of a succeeding sheet, and continuously drive the feeding motor so that the conveying speed of the succeeding sheet by the feeding motor becomes higher than that of the preceding sheet after the detection sensor detects the leading edge of the succeeding sheet.

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

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 the 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 skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

Printing apparatus and control method therefor

Printing apparatus, method and storage medium for conveying sheets intermittently to printhead while forming overlaps state

The present invention provides a printing apparatus. The printing apparatus includes a feeding unit, a pair of rollers configured to nip a printing medium and to convey the printing medium fed by the feeding unit, a printing unit and a control unit. The control unit can execute successive overlapped conveyance in which the pair of rollers nip an overlapping portion between a trailing edge of a preceding printing medium and a leading edge of a succeeding printing medium and convey them. The control unit executes the successive overlapped conveyance at least on condition that printing of the preceding printing medium by the printing unit has ended.

Printing apparatus and control method

A printing apparatus comprises a feeding roller configured to feed a printing sheet, a conveyance roller configured to convey the printing sheet, a printing unit configured to print on the printing sheet, a conveyance control unit configured to control conveyance of printing sheets so that a trailing edge of a preceding sheet and a leading edge of a succeeding sheet overlap each other, an acquisition unit configured to acquire, before completion of a printing operation of the preceding sheet, information of a leading edge position of the succeeding sheet, and a determination unit configured to determine 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 in accordance with the leading edge position of the succeeding sheet.
