Abstract
A device for storing and supplying an active liquid in an ink jet printhead including: an ink injector for jetting ink stored in an ink storage tank; and an active liquid storage tank mounted in close contact with one side of the bottom of the ink storage tank, storing an active liquid to be supplied to the ink injector, the ink injector having a single fluid path formed therein so as for the active liquid to be circulated and returned to the active liquid storage tank, the device having such a fluid path as to supply the active liquid between the heating chambers in the ink injector, cooling the heating chambers rapidly with the high speed of printing, and making it possible to check the completion of injection of the active liquid through feeding and circulating apertures.
Claims20
A device for storing and supplying an active liquid in an ink jet printhead, comprising:
- an ink injector for jetting ink stored in an ink storage tank, the ink injector having a single fluid path therein for the active liquid, the single fluid path being separate from another path for the ink to be jetted from the ink injector;
- and
- an active liquid storage tank mounted in close contact with at least one side of the bottom of the ink storage tank, said active liquid storage tank for storing said active liquid to be supplied to the ink injector, said active liquid functioning as a media for use in formation of ink drops from the ink, and the single fluid path for circulating the active liquid from the active liquid storage tank through the ink injector for return of the active liquid to the active liquid storage tank.
A device for storing and supplying an active liquid in an inkjet printhead, comprising:
- an ink injector for jetting ink stored in an ink storage tank, the ink injector having a single fluid path formed in the ink injector for circulating the active liquid, the active liquid functioning as a media for use in formation of ink drops from the ink, the single fluid path being separate from another path for the ink to be jetted from the ink injector, the single fluid path including a first common ink feeding aperture for receiving the active liquid, a plurality of heating chambers, and a first common ink circulating aperture;
- a first channel section disposed in accord with the first common ink feeding aperture of the ink injector;
- a second channel section disposed in accord with the first common ink circulating aperture of the ink injector;
- and
- an active liquid storage tank having a first storage section and a second storage section, the first storage section for storing the active liquid to be supplied to the ink injector through the first channel section, the second storage section for storing the active liquid supplied to the ink injector after the active liquid has been circulated in the ink injector for return of the active liquid to the active liquid storage tank through the second channel section.
