摘要： In a print cartridge according to the preferred embodiment of the invention, a polymer tape having orifices formed therein and containing conductive traces has a substrate containing heater elements affixed to a back surface of the tape. Each of the heater elements in the substrate is located substantially behind each of the orifices. The edges of the nozzle member overlap the edges of the substrate, and the back surface of the tape is sealed with respect to an ink reservoir so that a seal substantially circumscribes the substrate. This allows ink to flow around the side edges of the substrate and into vaporization chambers associated with each orifice. The conductive traces on the tape are attached to electrodes along the shorter side edges of the substrate so as not to interfere with the edge-feed of ink along the longer edges of the substrate. A demultiplexer on the substrate requires relatively few electrodes to be formed on the substrate for supplying energization signals to the numerous heater elements formed on the substrate.

摘要： An ink fill slot can be precisely manufactured in a substrate utilizing photolithographic techniques with chemical etching, plasma etching, or a combination thereof. These methods may be used in conjunction with laser ablation, mechanical abrasion, or electromechanical machining to remove additional substrate material in desired areas. The ink fill slots are appropriately configured to provide the requisite volume of ink at increasingly higher frequency of operation of the printhead by means of an extended portion that results in a reduced shelf length and thus reduced fluid impedance imparted to the ink. The extended portion is precisely etched to controllably align it with other elements of the printhead.

摘要： An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member.

摘要： Described herein is a monolithic printhead formed using integrated circuit techniques. Thin film layers, including ink ejection elements, are formed on a top surface of a silicon substrate. The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. A trench is etched in the bottom surface of the substrate so that ink can flow into the trench and into each ink ejection chamber through the ink feed holes formed in the thin film layers. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers. A phosphosilicate glass (PSG) layer, providing an insulation layer beneath the resistive layers, is etched back from the ink feed holes and is protected by a passivation layer to prevent the ink from interacting with the PSG layer. Other layers may also be protected from the ink by being etched back.

摘要： An ink jet print head having a substrate with an upper surface, and an ink supply conduit passing through the substrate. An array of independently addressable ink energizing elements are attached to the upper surface of the substrate. An orifice layer has a lower surface conformally connected to the upper surface of the substrate, and has an exterior surface facing away from the substrate. The orifice layer defines a plurality of firing chambers providing communication to the ink energizing elements, and each of the orifices is positioned in registration with a respective single ink energizing element. The exterior surface defines a plurality of nozzle apertures, each providing the upper terminus of a single firing chamber. Each of the firing chambers is laterally separated from all other firing chambers by a septum portion of the orifice layer.
