Abstract:
A printhead includes a chamber layer and at least two orifice layers. A first orifice layer is disposed on the chamber layer, and a second orifice layer is disposed on the first orifice layer. The second orifice layer has at least one counterbore formed therein. A first nozzle is formed through both orifice layers and produces droplets of a first drop weight. A second nozzle is formed through the first orifice layer, coincident with the counterbore, and produces droplets of a second drop weight that is different than the first drop weight. In one embodiment, the printhead is used in a stand-alone fluid-dispensing device.
