摘要： An inkjet print cartridge (10) comprises a substrate (28) having a plurality of ink firing chambers (130) along a top surface of said substrate and a first outer edge (86) in close proximity to the ink firing chambers. The ink firing chambers are arranged in first and second arrays and with the firing chambers spaced so as to provide 600 dots per inch printing. An ink channel connects an ink reservoir with the chambers, and include a primary channel (52) connected to the reservoir and to a secondary channel. The primary channel (52) allows ink to flow from the reservoir, around the first outer edge to the secondary channel so as to be proximate to the ink firing chambers. A separate inlet passage (132) for each chamber connects the secondary channel with the chamber for allowing high frequency refill. A group of firing chambers in adjacent relationship forms a primitive (P1-P14) in which only one chamber is activated at a time. A circuit (78) on the substrate connects to the firing elements, while a second circuit (36) on the cartridge connects to the first circuit means, for transmitting firing signals to ink firing elements at a frequency greater than 9 kHz.

摘要： A nozzle member (16) containing an array of orifices (17) has a substrate (28), having heater elements (70) formed thereon, affixed to a back surface of the nozzle member. Ink is supplied from an ink reservoir (12) to the orifices by a fluid channel (80) within a barrier layer (30) between the nozzle member and the substrate. The nozzle member is adhesively sealed with respect to the ink reservoir body by forming an ink seal (90) circumscribing the substrate, between the back surface of the nozzle member and the body.

摘要： An inkjet printhead (14) includes a barrier layer (134) containing ink channels (132) and firing chambers (130) and located between a rectangular substrate (28) and a nozzle member (16) containing an array of orifices (17). The substrate contains two spaced linear arrays of ink ejection elements (70). The ink channels have ink entrances running along two opposite edges (86) of the substrate so that ink (88) flowing around the edges of the substrate gains 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 neighbouring ink ejection elements from each other in each primitive (P1-P14) grouping in the linear array, combining short shelf length with damped ink inlet channels (132), 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 is accomplished by densely positioning the ink ejection elements in each linear array.
