  • Patent number: 8287066
    Abstract: This invention pertains to a drop-on-demand ink jet printing method, more particularly to a method of printing wherein a purge image is logically combined with a selected image so as to insure a desired amount of drop firing from every jet of an ink jet printhead for every page printed. The inventive method avoids image defects that could otherwise occur as a result of faulty drop firing from infrequently used nozzles. Purge image data that specifies the deposition of at least one ink dot on at least one predetermined pixel location on each of the plurality of image scanlines is constructed and stored in a purge image memory accessible by the printing apparatus. Imperceptible purge image patterns are constructed having blue noise spatial frequency characteristics and optical density levels equal to or less than 0.01 OD above print medium base OD. A plurality of purge image data sets are constructed and stored for retrieval to adapt to a variety of conditions.

Since the heat generating portion is cooled down by the air sucked from the suction port by the suction device, it is possible to reduce a possibility of the heat of the heat generating section being transferred to the jetting head unit, and destabilizing an operation of the jetting head unit. Moreover, since the suction port opens near the nozzle, it is possible to suck fine liquid droplets together with air around the nozzle.

    Abstract: A multicolor-use ink cartridge has obverse surface-side ink chambers and formed on an obverse surface side of a horizontal plate portion of a rigid plastic plate and reverse surface-side ink chambers and formed on a reverse surface side thereof. Since these ink chambers are arranged in a breadthwise direction so as to be staggered in a mutually overlapping state with the horizontal plate portion interposed therebetween, it is possible to make small the dimension in a direction in which the ink chambers are arranged. The respective ink chambers are formed by joining flat portions of three-dimensionally molded flexible plastic films to obverse surface-side recesses formed on the obverse surface of the horizontal plate portion and reverse surface-side recesses formed on the reverse surface thereof, respectively. Therefore, it is possible to form ink chambers having high sealability.

  • Patent number: 8104867
    Abstract: A liquid droplet jetting apparatus includes a jetting head unit which has a nozzle which jets droplets of a liquid, and a heat generating section, a suction port which is formed in the jetting head unit, and which opens near the nozzle, and a suction device which sucks air around the nozzle from the suction port, and cools down the heat generating section of the jetting head unit by the air which is sucked. Since the heat generating portion is cooled down by the air sucked from the suction port by the suction device, it is possible to reduce a possibility of the heat of the heat generating section being transferred to the jetting head unit, and destabilizing an operation of the jetting head unit. Moreover, since the suction port opens near the nozzle, it is possible to suck fine liquid droplets together with air around the nozzle.
