    Abstract: Disclosed is a print cartridge for an inkjet printer includes a flexible circuit having a nozzle member formed therein, the nozzle member including a plurality of ink orifices and the flexible circuit having window openings therein. The window openings expose electrical leads on the flexible circuit. A substrate containing a plurality of heating elements and associated ink ejection chambers, and having electrodes to which the electrical leads are bonded, is mounted on the back surface of the nozzle member. Each heating element is located proximate to an associated ink orifice. The back surface of the nozzle member extending over two or more outer edges of the substrate. A print cartridge body having a headland portion located proximate to the back surface of the nozzle member and including an inner raised wall circumscribing the substrate. The inner raised wall having an adhesive support surface formed thereon and having wall openings therein. The wall openings having an adhesive support surface. An adhesive layer is located between the back surface of the nozzle member and the inner raised wall and wall openings therein to affix the nozzle member to the headland and form an adhesive ink seal. The adhesive layer is located on the adhesive support surface of the inner raised wall and along the adhesive support surface within the wall openings therein and within the window openings so as to encapsulate the electrical leads bonded to the substrate electrodes.

    Abstract: A printing method that includes supplying ink from an ink reservoir through an ink channel that connects the ink reservoir with ink ejection chambers formed on a first surface of a substrate. The ink channel is connected at a first end to the ink reservoir and at a second end to a separate inlet passage for refilling each of the ink ejection chambers with ink. A group of the ink ejection chambers in adjacent relationship forms one of a plurality of primitives on the first surface of the substrate in which only a maximum of one of the ink ejection chambers is energized at a time. An ejection element within one of the ink ejection chambers is energized to cause the plurality of ink drops to be ejected onto a media surface at a single pixel location in a single pass of the substrate over the media surface.
