    摘要： An inkjet print cartridge 18 uses at least one groove 64 to supply ink 112 from an ink reservoir 38 to the fluid channel 78, 74, which includes an ink ejection chamber 74, such that foreign particles within the ink supply are filtered out by the grooves 64 so as not to block the fluid channel 74,78, 80. In one embodiment, a barrier layer 62 between a substrate 60 and nozzle member 48 contains the ink ejection chamber 74 which is in communication with a plenum 78 via a flow restrictor 80, such as pinch points. The nozzle member 48 includes an array of orifices 84 and grooves 64. The substrate 60 includes two linear arrays of ink ejection elements 72, such as heater elements, and each orifice 84 in the nozzle member 48 is associated with an ink ejection chamber 74 and ink ejection element 72. A plurality of grooves 64 is likewise associated with each plenum 78. The plurality of grooves 64 in the nozzle member 48 supply ink 112 into each plenum 78, which in turn supplies ink 112 to the ink ejection chamber 74.

    摘要： An ink-jet swath printer employing a cartridge (50) with a spring bag primary reservoir (62) and an auxiliary ink reservoir (230) interconnected via a tube (240) to form a closed ink replenishment system. The primary reservoir creates a negative pressure which draws ink from the auxiliary reservoir as ink is expelled from the cartridge printhead (76) during printing operations. The auxiliary reservoir can either be mounted on the cartridge carriage (210) or on the printer body (202). The auxiliary reservoir is a large capacity collapsible bag mounted below the level of the printhead to establish an ink pressure head at the primary reservoir connection which is not so large as to destroy or diminish the negative pressure and allow ink to drool from the printhead, yet is sufficient to permit replenishment of the primary reservoir to avoid printhead ink starvation.

    摘要： A closed ink replenishment system for replenishing the supply of ink in negative pressure spring-bag reservoirs in a printer/plotter (1000). A tube (1310-1340) runs between each cartridge reservoir and an auxiliary reservoir (1410-1440) mounted to the printer/plotter frame to form the closed ink system. As ink is depleted from the spring-bag reservoir during printing operation, the negative pressure in the cartridge increases, drawing ink through the tube from the auxiliary reservoir into the cartridge until the negative pressure decreases to an equilibrium point. As a result, the volume of ink within the spring-bag reservoir remains substantially constant so long as there is ink remaining within the auxiliary reservoir. This maintains the print quality. The auxiliary reservoir is a flat bag mounted on a spring-biased platform (1510), which acts as a height regulating system. As ink is depleted from the auxiliary bag, the height of the platform and bag increases to maintain a constant pressure and elevation head at the spring-bag reservoir.
