ABSTRACT:
A nozzle device for an inkjet printhead includes a substrate assembly defining an ink supply; a chamber-defining layer defining a nozzle chamber in fluid communication with a nozzle opening and the ink supply; an actuating arm coupled to the substrate assembly and terminating in a paddle separating the ink supply and nozzle chamber, the actuating arm configured to pivot during actuation to cause ink within the nozzle chamber to be ejected out through the nozzle opening; and a movement sensor configured to determine the degree or rate of pivotal movement of the actuating arm. The actuating arm further includes a bridge between the paddle and the thermal bend portion which supports a portion of the chamber-defining layer.
