  • Patent number: 11845627
    Abstract: A printing apparatus includes a feeding roller, a conveyance roller, a first driving unit configured to drive the conveyance roller, a second driving unit configured to drive the feeding roller, a control unit configured to control the first and second driving units, a detection unit configured to detect an error related to the second driving unit, and a determination unit configured to determine, when the detection unit has detected the error related to the second driving unit, whether to continue the conveyance of a first print medium based on a leading edge position of a second print medium. In a case in which an error is detected by the detection unit, the control unit controls the conveyance of the first print medium by the conveyance roller based on a determination result of the determination unit.

  • Patent number: 11562187
    Abstract: A printing apparatus includes a printing head to move in a first direction, a conveying roller to convey the printing medium in a second direction intersecting with the first direction, and a housing to house the printing head and the conveying roller and be expandable and contractible in the first direction. The printing apparatus performs predetermined notification based on information related to a length of the housing in the first direction, wherein the conveying roller is incapable of conveying the printing medium having a predetermined size when the length of the housing in the first direction is a first length and conveys the printing medium having the predetermined size in a case where the length is a second length larger than the first length. The predetermined notification is performed based on the information related to the length of the housing indicating information corresponding to the first length.

  • Patent number: 11403501
    Abstract: In a printing apparatus, a control unit stops paper feeding driven by a driving unit for driving a paper feeding roller in response to a timing at which a printing medium reaches a conveying roller, if the printing medium has a first size, and stops paper feeding driven by the driving unit before a detection unit located upstream of the conveying roller detects the printing medium if the printing medium has a second size smaller than the first size.

  • Patent number: 11053089
    Abstract: A printing apparatus includes a conveyance unit configured to convey a tray on which a printing medium is placed, a printing unit configured to perform printing on a print surface of a printing medium on the tray based on a print job, and a first detection unit configured to detect a relative position relationship between the tray and a printing medium placed on the tray. In addition, a control unit is configured to control the printing unit not to perform printing in a case where the first detection unit detects that the printing medium is not placed at an appropriate position, and a selecting unit is configured to select whether to continue printing irrespective of results of the detection by the first detection unit.

  • Publication number: 20200380321
    Abstract: The invention provides a printing apparatus, a printing control method, and a processing apparatus, which suppress the occurrence of rework after a start of a printing operation and suppress an output of a printing result not intended by a user due to a mismatch between a state of expansion or contraction and print settings. To this end, printing is performed in print processing by determining whether or not an operable state is established which is a state of expanding a housing to a second position.

  • Publication number: 20200039773
    Abstract: An object of the present invention is to prevent printing processing from being performed in a case where a printing medium is not placed correctly on a tray because of an erroneous operation of a user, or the like. The present invention is a printing apparatus including: a conveyance unit configured to convey a tray on which a printing medium is placed; a printing unit configured to perform printing on a print surface of a printing medium on the tray based on a print job; and a first detection unit configured to detect a relative position relationship between the tray and a printing medium placed on the tray, and the printing apparatus has a first notification unit configured to give a notification of an error indicating that a placing position of the printing medium is not an appropriate position based on detection results by the first detection unit.

  • Patent number: 10343426
    Abstract: A printing apparatus includes a printing unit that prints on a printing medium, and a discharge tray that is movable, by a motor, between an accommodated position and an extended position. An external tray is detachably attached to the printing apparatus. An operation unit displays a screen on a display screen to receive a moving instruction for moving the discharge tray, and confirmation of removal of the printing medium from the discharge tray. When the operation unit receives a moving instruction for moving the discharge tray from the extended position to the accommodated position, a control unit moves the discharge tray after receiving confirmation from a user, via the screen, that the printing medium has been removed from the discharge tray, and, when the external tray is attached to the printing apparatus, the control unit does not move the discharge tray from the accommodated position to the extended position.
