  • Patent number: 11230109
    Abstract: In a continuous ink jet printer for use with pigmented ink, the entrance to the ink path (81), (35) from the interior of the ink tank (27) to the ink pump (31) is made up of a plurality of small inlet openings, which may be provided by nozzles 85 formed in a shroud 83 that fits around an ink filter (33) in the ink tank (27). The openings are provided at the bottom of the ink tank (27), close to the floor, and face parallel to the floor or at least partially towards it. If the ink pump (31) is driven in reverse, any ink in the ink path is driven at speed out through the inlet openings into the interior of the ink tank (27), followed by air. This tends to disperse pigment that may have settled to the bottom on the ink tank (27).

  • Patent number: 10226940
    Abstract: Systems and related methods are described for circulating and printing fluid onto a printer media. In one example, a system can include an air isolation chamber to pool printing fluid circulated within the system. The air isolation chamber can be fluidly connected to a printhead assembly to eject a portion of the printing fluid onto the printer media. The system can further include a pump to pump printing fluid from the air isolation chamber to the printhead assembly. The system can further include a pressure control valve along a return line between the air isolation chamber and the printhead assembly to regulate the flow of unejected printing fluid to the air isolation chamber to control printing fluid pressure over the printhead assembly.

  • Patent number: 9956773
    Abstract: A wall-shaped enclosure that forms a space which can accommodate a head chip is formed in a projecting manner at a lower end of a lower case member. Since a cylindrical thick part is formed at the lower end of the lower case member, the lower case member is unlikely to be bent, particularly around the wall-shaped enclosure and a part where the wall-shaped enclosure is disposed. The head chip that is disposed in the space of the lower case member which is unlikely to be bent is unlikely to be subjected to an external force, and the cover member absorbs torsion generated between the head chip and the lower case member so that the head chip is even more unlikely to be subjected to the external force.
