  • Publication number: 20200047529
    Abstract: There is provided with a printing apparatus. A transfer member cyclically passes a formation area and a transfer area of an ink image. A print unit forms an ink image on the transfer member by discharging ink to the transfer member in the formation area. A conveyance drum conveys a print medium and to which an ink image is transferred from the transfer member in the transfer area. A cleaning unit cleans the conveyance drum at a cleaning position where the cleaning unit contacts the conveyance drum. A displacing unit separates the cleaning unit from the cleaning position when the print medium passes the cleaning position.

  • Patent number: 9162507
    Abstract: A printing apparatus includes a first circulation pump which is provided in a channel between a print head and a first storage tank and which supplies ink from a second storage tank to the print head. The printing apparatus further includes a second circulation pump which is provided in a channel between the first storage tank and the second storage tank which supplies ink from the first storage tank to the second storage tank. The printing apparatus further includes a control unit which controls the driving of the first circulation pump and second circulation pump, and a detecting unit which detects the amount of ink stored in the second storage tank. The control unit controls the driving of the second circulation pump on the basis of a detection result by the detecting unit.
