Patent ID: 8485638

Claim:
An inkjet printhead comprising: a substrate comprising a drive circuitry layer; a plurality of nozzle assemblies disposed on an upper surface of said substrate and arranged in one or more nozzle rows extending longitudinally along said printhead, each nozzle assembly comprising: a nozzle chamber having a floor defined by said upper surface, a roof spaced apart from said floor, and an actuator for ejecting ink from a nozzle opening defined in said roof; a nozzle plate extending across said printhead, said nozzle plate at least partially defining said roofs; and at least one conductive track disposed on said nozzle plate, said conductive track extending longitudinally along said printhead and parallel with said nozzle rows, wherein said conductive track is connected to a common reference plane in said drive circuitry layer via a plurality of conductor posts extending between the drive circuitry layer and the conductive track.
