  • Patent number: 9443173
    Abstract: A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from a stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other, and a determination unit which determines whether to convey the succeeding sheet to a position facing the printing unit while keeping an overlap state between the preceding sheet and the succeeding sheet. The determination unit determines whether the printing sheet is suitable for overlap conveyance, and if the determination unit determines that the printing sheet is unsuitable for overlap conveyance, the conveyance control unit conveys the succeeding sheet while the succeeding sheet does not overlap the preceding sheet.

  • Patent number: 9427985
    Abstract: A printing apparatus includes a feeding unit configured to feed a printing sheet stacked on a stacking unit, a conveying unit configured to convey the printing sheet fed by the feeding unit, a printing unit configured to print the printing sheet conveyed by the conveying unit, and a control unit configured to control the feeding unit and the conveying unit. When continuously printing on the first surfaces of a plurality of printing sheets, the feeding unit forms an overlap state in which a trailing edge of a preceding sheet and a leading edge of a succeeding sheet overlap each other, and the conveying unit conveys the printing sheets while keeping the overlap state. When performing double-sided printing on the first surface and the second surface of the printing sheet, the feeding unit does not form the overlap state.

  • Patent number: 8955956
    Abstract: In a printing apparatus improvement of drying ability and reduction of consumed power are concurrently achieved by improving the efficiency of drying ink. More concretely, hot air is blown onto a print medium printed by ink, and a portion of the blown hot air is recovered and blown again. Before the hot air is blown, the print medium is heated by a preheating unit, making it higher than the dew point temperature of the blown hot air.

  • Patent number: 8727526
    Abstract: In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.
