摘要： This invention provides an improved ink flow path between an ink reservoir and vaporization chambers in an inkjet printhead. In the preferred embodiment, a barrier layer containing ink channels and vaporization chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two linear arrays of heater elements, and each orifice in the nozzle member is associated with a vaporization chamber and heater element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edge of the substrate gain access to the ink channels and to the vaporization chambers.

摘要： An inkjet printhead includes a compact substrate having a pair of elongated edge portions for ink channel architecture, a central interior for substrate circuitry, and a pair of truncated end portions for mounting and for electrical interconnects. The ink channel architecture includes a plurality of ink vaporization chambers each having a firing resistor therein, as well as ink feed channels communicating through an ink passage from an underside of the substrate around both edges of the substrate to the vaporization chambers. The central interior portion excludes any ink channel architecture thereby enhancing the structural stability

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 improved ink flow path between an ink reservoir and ink ejection chambers in an inkjet printhead is disclosed along with a preferred printhead architecture. In the preferred embodiment, a barrier layer containing ink channels and firing chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two spaced apart arrays of ink ejection elements, and each orifice in the nozzle member is associated with a firing chamber and ink ejection element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edges of the substrate gain access to the ink channels and to the firing chambers. High speed printing capability with a firing frequency up to 12 KHz is accomplished by offsetting neighboring ink ejection elements from each other in each primitive grouping in the linear array, combining short shelf length with damped ink inlet channels, and then firing only one ink ejection element at a time in each primitive grouping thereby minimizing undesirable interference such as fluidic crosstalk between closely adjacent ink firing chambers. High resolution printing capability for at least 600 dots-per-inch by the printhead as a whole is accomplished by densely positioning the ink ejection elements in each linear array of ink ejection elements.
