  • Patent number: 8439471
    Abstract: An ink jet recording apparatus for effecting recording using a recording head for ejecting ink, the ink jet recording apparatus including a heating section for heating the recording head, a detecting unit for detecting a temperature of the recording head, a setting unit for setting a target temperature of the recording head, and a controller for controlling the target temperature of the recording head at or above the target temperature. The controller controls the temperature by heating control for heating the recording head and by diffusing control for diffusing the heat supplied by the heating control.
    Type: Grant

  • Patent number: 7967411
    Abstract: An apparatus includes a liquid ejecting head capable of ejecting liquid from a plurality of ejection ports by driving a plurality of ejection energy generation elements corresponding to the plurality of ejection portions. The apparatus includes a wiping mechanism capable of wiping an ejection port face in which a plurality of ejection ports is arranged in the liquid ejecting head. The ink ejection from the plurality of ejection ports is performed in a manner of a plurality of divisions. A time interval from a last wiping to a next wiping is adjusted according to an interval of the ejection energy generating elements corresponding to an adjacent ejection port.

  • Patent number: 7506949
    Abstract: The invention obtains superior printing quality even when printing at high speed, thinning the number of multi-pass inkjet printing scans. The inkjet printing apparatus comprises a printhead composed of multiple printing element arrays that are arranged corresponding to ink colors in the main scanning direction, and a unit that makes the printing duty of at least one printing element array vary with regard to the printing duty of other printing element arrays, according to the printing element arrays.
