Patent number: 11562187Abstract: 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.Type: GrantFiled: May 27, 2020Date of Patent: January 24, 2023Assignee: CANON KABUSHIKI KAISHAInventors: Toshiyuki Kuroda, Kazuhisa Fujino, Naoki Aoyama, Syunichi Kunihiro, Hiroshi Suzuki

Publication number: 20200380321Abstract: 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.Type: ApplicationFiled: May 27, 2020Publication date: December 3, 2020Inventors: Toshiyuki Kuroda, Kazuhisa Fujino, Naoki Aoyama, Syunichi Kunihiro, Hiroshi Suzuki

Patent number: 10343426Abstract: 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.Type: GrantFiled: June 22, 2017Date of Patent: July 9, 2019Assignee: Canon Kabushiki KaishaInventor: Kazuhisa Fujino
