  • Patent number: 6969149
    Abstract: A print head for a line printer in which errors between print head chips and another component are reduced and ink leakage is prevented, and in which heat generated in print head chips is efficiently dissipated without making the structure of the print head complex or increasing the size of the print head. A plurality of print head chips (11) are arranged along an ink path (20) and are disposed on both sides of the ink path in a zigzag pattern. Dummy chips (21) which do not eject ink are disposed at regions between the print head chips (11) arranged along the ink path (20). In addition, an ink-path member (23) is provided, at least a part of the ink-path member (23) which includes portions adhered to the print head chips (11) being composed of a material having a high thermal conductivity, so that the ink-path member (23) also serves as heat-dissipating means which dissipates heat generated in the print head chips (11).

  • Publication number: 20050225613
    Abstract: A distribution container containing storage liquid is mounted in a cartridge holding section of a line head to substitute for an ink cartridge during transportation and storage of the line head. The storage liquid prevents air from flowing into the line head through nozzles, and thereby avoids discharging failure, for example, no discharging or insufficient discharging of ink.

  • Publication number: 20050151778
    Abstract: A liquid ejection head including a reusable nozzle cap and head cap unit that prevents ink from leaking during transport and storage. When the liquid ejection head is in use, the nozzle cap can be readily detached from the liquid ejection head without damaging an ejection surface of a nozzle sheet from which ink is ejected. The liquid ejection head can also be used with a large nozzle sheet. The nozzle cap is incorporated in the liquid ejection head that ejects ink in an ink reservoir through nozzles in the nozzle sheet. Stoppers are disposed below the ejection surface of the nozzle sheet to cover the nozzles, thereby preventing ink from leaking. The stoppers are composed of a resilient material that does not adhere to the nozzle sheet and that inhibits ink from passing therethrough.

  • Publication number: 20050116999
    Abstract: A negative pressure generated inside a liquid-ejecting head can circulate liquid between the liquid-ejecting head and a liquid tank, prevent the liquid from leaking out of nozzles while the liquid is circulating, and remove bubbles contained in the liquid. A head cartridge includes a printhead ejecting ink from ink-ejecting nozzles formed in a nozzle plate of the printhead, an ink-supplying conduit supplying the ink from an ink tank to an ink chamber in the printhead, an ink-refluxing conduit refluxing the ink from the printhead to the ink tank, and a liquid-delivering pump disposed on the ink-refluxing conduit and circulating the ink between the printhead and the ink tank. The liquid-delivering pump is driven to generate a negative pressure inside the printhead to circulate the ink between the printhead and the ink tank.

  • Publication number: 20040125172
    Abstract: In a liquid-ejecting method for ejecting liquid contained in a liquid chamber from a nozzle as a liquid droplet group, the ejection amount of each liquid droplet of the continuously ejected liquid-droplet group can be stabilized corresponding to a wide frequency band of a pulse signal. Also, when one pixel is formed with a plurality of liquid droplets using a head capable of deflecting the ejecting direction of the liquid droplet, the image quality is improved by reducing the landing positional displacement between plural liquid droplets for forming the one pixel.
