ABSTRACT:
A printhead integrated circuit is provided. The integrated circuit includes a substrate, a plurality of inkjet nozzles formed on the substrate and drive circuitry connected to the inkjet nozzles. Each inkjet nozzle includes a nozzle chamber for storing ink to be ejected, at least one moveable actuator paddle forming at least a portion of a first wall of the nozzle chamber and an ink ejection opening defined in the first wall. In use, actuation of the actuator paddle causes ejection of ink from the nozzle.
