    摘要: A micro-fluid ejection head structure having multiple arrays of fluid ejection actuators. The structure includes a semiconductor substrate having a first array of fluid ejection actuators for ejecting a first fluid therefrom, and a second array of fluid ejection actuators for ejecting a second fluid therefrom. The first array of fluid ejection actuators is disposed in a first location on the substrate, and the second array of fluid ejection actuators is disposed in a second location on the substrate. A thick film layer having a thickness is attached adjacent the semiconductor substrate. The thick film layer has fluid flow channels formed therein solely for the first array of fluid ejection actuators. A nozzle plate is attached to the thick film layer opposite the semiconductor substrate. The nozzle plate has fluid flow channels formed therein for both the first array of fluid ejection actuators and the second array of fluid ejection actuators.

    摘要: Flow features in an inkjet printhead. The flow features can include a plurality of first channels, each of the plurality of first channels having a first length and positioned to fluidly communicate with an ink reservoir, and each of the plurality of first channels terminating in a first nozzle. The flow features can further include a plurality of second channels, each of the plurality of second channels having a second length greater than the first length and positioned to fluidly communicate with the ink reservoir, each of the plurality of second channels terminating in a second nozzle, each second nozzle being larger than each first nozzle.
