ABSTRACT:
A nozzle for an inkjet printer includes a roof layer defining a nozzle port through which ink is ejected; a substrate layer fast with the roof layer and defining a nozzle chamber wall; and an actuator assembly fast with the substrate layer and including a support. The actuator assembly includes a lever arm cantilevered to extend from the support and terminating in a piston. The piston is positioned within a nozzle chamber defined by the nozzle chamber wall. The nozzle chamber wall is provided along a height thereof with a gap, the gap being dimensioned to pass the lever arm therethrough.
