  • Patent number: 10611140
    Abstract: A printing apparatus according to an embodiment of this invention brings, out of a cleaning unit that cleans a transfer member in contact with a transfer member and an application unit that applies a reactive liquid with ink to the transfer member, the cleaning unit into contact with the transfer member to clean the transfer member by the cleaning unit at the start of the printing operation. Alternatively, out of the application unit and an absorbing unit that absorbs a liquid component from the reactive liquid applied by the application unit in contact with the transfer member, the printing apparatus brings the application unit into contact with the transfer member to apply the reactive liquid by the application unit.

  • Patent number: 10500839
    Abstract: An inkjet printing apparatus includes a printhead configured to form an image by discharging ink to a transfer member, a transfer unit configured to transfer the image from the transfer member to a print medium, and an application unit configured to apply a first liquid to the transfer member prior to formation of the image by the printhead. The inkjet printing apparatus also includes a first drying unit configured to dry the first liquid applied to the transfer member by the application unit by blowing air using a first air blower before the ink is discharged by the printhead to the transfer member.

  • Patent number: 10486417
    Abstract: A printing apparatus includes a transfer member that rotates, a printhead that forms an image on the transfer member, and a transfer unit that transfers the image to a print medium. An application unit, provided at a downstream side of an area, at which the transfer unit transfers the image to the print medium, in a rotation direction of the transfer member, applies a cleaning liquid to a region on the transfer member after the image is transferred to the print medium. In addition, a collecting unit, provided between the printhead and the application unit, in the rotation direction of the transfer member, includes a collection roller that rotates in contact with the transfer member, in a direction opposite to the rotation direction of the transfer member, for collecting the cleaning liquid applied to the transfer member by the application unit.
