  • Patent number: 7959255
    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.

  • Patent number: 7798601
    Abstract: An amount of deposit in an ink receiving portion can be controlled using an inexpensive configuration which does not require any complicated mechanisms or control and which avoids increasing ink consumption. An ejection control section controls ejecting of ink from a printing section into an ink receiving portion. The printing section has a first ink ejecting portion that ejects ink that accumulates easily in the ink receiving portion and a second ink ejecting portion that ejects ink that is hard to accumulate in the ink receiving portion. The ejection control section changes the landing position, in the ink receiving portion, of the ink ejected from the ink ejecting portions depending on the status of accumulation of the ink in the ink receiving portion.

  • Patent number: 7771034
    Abstract: The invention relates to a fluidic arrangement for a printer. The arrangement includes an ink tank for storing ink, and an ink distribution assembly in fluid communication with the ink tank for supplying printhead integrated circuits (ICs) positioned thereon with ink from the ink tank. The arrangement also includes a valve arranged in an ink line between the ink distribution assembly and the ink tank, said valve configured to isolate ink in the ink tank from the printhead ICs whenever the printer is powered down. Further included is a pump located downstream from the ink distribution assembly, and a sump arranged in fluid communication with the pump for receiving excess ink from the ink distribution assembly.
