    摘要： A printhead is provided for an inkjet printer. The printhead includes a two-dimensional array of ink nozzle arrangements. Each nozzle arrangement includes a wafer portion defining both a nozzle chamber for storing ink and an ink supply channel in fluid communication with the nozzle chamber. A cover covers the nozzle chamber and defines a nozzle rim from which a plurality of supports extends outwardly. The cover includes a plurality of actuators extending inwardly toward the nozzle rim between respective pairs of adjacent supports and terminates in free ends. The actuators include internal heating elements which can be actuated so that the free ends reciprocate into and out of the nozzle chamber to eject ink out through the nozzle rim.

    摘要： An ink jet printhead nozzle arrangement includes a wafer substrate that defines side walls and an inlet opening of an ink chamber. Drive circuitry is arranged on the wafer substrate. A roof wall assembly defines a roof of the ink chamber and an ink ejection port in fluid communication with the ink chamber. The roof wall assembly includes a nozzle rim supported in general alignment with the inlet opening. A series of radially positioned actuators are each connected to the substrate to receive electrical drive signals, with free ends of the actuators terminating proximate the nozzle rim. The actuators are configured so that, on receipt of an electrical signal from the drive circuitry, said free ends of the actuators are displaced into the ink chamber to reduce a volume of the ink chamber and to eject ink from the ink ejection port.

    摘要： A method of redirecting ejected ink droplets from a printhead is provided. The method compries the steps of: (a) providing a printhead assembly comprising: a printhead including a plurality of nozzles for ejecting ink droplets onto a print medium, the plurality of nozzles being formed on an ink ejection surface of the printhead; and a nozzle guard positioned over the ink ejection surface, the nozzle guard having a corresponding plurality of channels therethrough, the channels being aligned with the nozzles such that ejected ink droplets pass through respective channels towards the print medium; and (b) ejecting ink droplets from the nozzles. The channels have hydrophobic sidewalls, such that misdirected ink droplets rebound off the sidewalls and continue through the channels towards the print medium.
