摘要： In order to reduce particle clogging of ink firing chambers in an inkjet printer printhead, the barrier layer is configured to have a plurality of inner barrier islands, each associated with a respective one of the heater resistors, disposed between an ink firing chamber and the ink plenum, to form two ink feed channels. The two ink feed channels are designed to have a right angle turn to prevent particles from entering the ink firing chamber. A plurality of outer barrier islands, having a number equal to twice the number of inner barrier islands, are disposed between the inner barrier islands and the ink plenum, and are configured in lines parallel to the lines of heater resistors to prevent particles from reaching the ink feed channels.

摘要： An inkjet printer printhead is coupled to an ink source and has a plurality of ink firing chambers dimensionally defined by a barrier layer disposed between a substrate and an orifice plate. Two ink feed channels are coupled to one ink firing chamber and are dimensionally defined, in part, by the barrier layer. One of these ink feed channels has a smoothly converging wide dimension inlet at the ink source and a narrow dimension outlet at the ink firing chamber. The other ink feed channel also has a converging wide dimension inlet at the ink source and a narrow dimension outlet at the ink firing chamber but has an "S" shaped wall contour to make it asymmetrical to the first ink feed channel. An island of the barrier layer separates one ink feed channel from the other ink feed channel serving the ink firing chamber. This island has an essentially flat wall surface disposed toward the ink firing chamber.
摘要翻译：喷墨打印机打印头联接到墨源并且具有由设置在基板和孔板之间的阻挡层尺寸限定的多个墨喷射室。两个墨水供给通道联接到一个墨水喷射室，并且部分地被阻挡层尺寸限定。这些供墨通道中的一个在墨源处具有平滑会聚的宽尺寸入口，并且在墨喷射室处具有窄尺寸的出口。另一个供墨通道在墨源处也具有会聚的宽尺寸的入口，并且在油墨喷射室处具有狭窄的尺寸出口，但是具有“S”形的壁轮廓，以使其与第一供墨通道不对称。阻挡层的一个岛将一个供墨通道与另一个用于喷墨室的供墨通道分开。该岛具有朝向油墨喷射室设置的基本平坦的壁表面。

摘要： A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.

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： 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： A variable optical density print system and method for continuous variation of the optical density among successive droplets expelled from the same nozzle, the print system comprising a fluid channel connected to a basis fluid supply and a fluid channel connected to a colorant concentrate fluid supply. Each fluid channel is in fluid communication with a single ink firing chamber. Appropriate amounts of basis fluid and colorant concentrate fluid are delivered to the firing chamber by briefly opening a microvalve positioned within each fluid channel. The fluids mix in the firing chamber and are then ejected as a single ink droplet which possesses a desired optical density.
