  • Patent number: 11833816
    Abstract: A printing apparatus according to an embodiment of this present invention includes a printhead with an orifice for discharging ink, and a recovery unit configured to perform recovery of the printhead by driving a print element of the printhead to discharge ink from the orifice. The apparatus makes a setting for a request for discharge recovery by the recovery unit after initialization processing performed upon power-on of the printing apparatus, and controls the recovery unit to execute one of first discharge recovery and second discharge recovery in which an ink discharge amount is smaller than in the first discharge recovery in accordance with the setting before a start of printing by the printhead.
    Type: Grant
    Filed: April 25, 2022
    Date of Patent: December 5, 2023

  • Patent number: 10427411
    Abstract: An ink-jet printing apparatus includes a print head having a first discharge port and a second discharge port, a cap, a suction unit connected to the cap for sucking ink from the print head, and a determining unit which determines one to be performed by the print head between a first printing operation using the first and second discharge ports and a second printing operation using the first discharge port only, wherein before the first printing operation, the suction unit is controlled to perform first and second suction operations sucking at different strengths. A storing unit further provided therein stores history information indicating the past performance of that the first printing operation. Before the second printing operation, the suction unit is controlled to perform the first suction operation only and, based on the history information after the printing operation, perform the second suction operation.
