摘要： A printhead for an inkjet printer employs asymmetric orifices, such as an egg-shaped orifice, at the surface of the orifice plate to cause the ink drop tail to be severed at a predictable location from the orifice. The controlled tail and diminished spray of an ink droplet expelled from the asymmetric orifice results in improved edge roughness and improved quality of print.

摘要： A method and apparatus for improving inkjet print quality uses a printhead having an array using a plurality of nozzles in sets in each drop generator mechanism. Where a conventional inkjet pen fires a single droplet of ink at a target pixel per firing cycle, the present invention simultaneously ejects a plurality of droplets at different subdivisions of pixels. Drop generators of a printhead array includes a plurality of nozzles for the drop generators arranged such that the light absorption of the sum of the simultaneously ejected ink droplets is like that of conventionally ejected drops but distributed over an area of the printed medium greater than that of a conventional target pixel.

摘要： An orifice membrane is provided an articulation parallel to the rows of orifices and between the area of the orifice membrane secured to the cartridge body and the area of the orifice membrane secured to the barrier layer of the heater resistor substrate. The reduced stress at the orifices reduces the distortion of the bore axis of the orifices.

摘要： A method and apparatus for improving ink-jet print quality uses a print head having an array using a plurality of nozzles in sets in each drop generator mechanism. Where a conventional ink-jet pen fires a single droplet of ink at a pixel per firing cycle, the present invention fires a plurality of droplets at different subdivisions of pixels. The particular array design may vary from ink-to-ink or pen-to-pen. Each drop generator of a print head array includes a plurality of nozzles wherein each of the nozzles has an exit orifice with an areal dimension, and produces an ink droplet that produces a dot on adjacent print media wherein the dot has an areal dimension, less than the areal dimension of a pixel to be printed. Dots are printed in a pattern for each pixel wherein print quality is achieved that approximates a higher resolution print made by conventional ink-jet methodologies.

摘要： The configuration of an ink inlet through which flows ink into a chamber for expulsion from the chamber by a thermal process is such that a vapor bubble generated by the thermal process to eject ink from the chamber expands to simultaneously occlude the inlet, thereby to separate the ink within the chamber from ink within a channel that is in fluid communication with the inlet. The separation eliminates a liquid path between the chamber and the channel so that substantially no ink is blown back into the channel as the bubble expands, thereby improving the thermal efficiency of the process.

摘要： A system for receiving and recycling ink comprises a print cartridge having a printhead, and an ink supply reservoir fluidly connected to the print cartridge and a seal member coupled to the ink supply reservoir. The seal member defines a fluid path into the reservoir and the print cartridge engages the seal member so that ink spit from the printhead flows through the fluid path into the reservoir.
