A nozzle assembly is provided for an inkjet printhead. The
nozzle assembly includes a substrate assembly defining an
ink inlet. A nozzle extends from the substrate assembly in
register with the ink inlet and defines an opening through
which ink can be ejected. A lever arm extends from the
nozzle. A thermal bend actuator assembly is mounted to the
substrate assembly and engages with the lever arm so that,
upon actuation, the lever arm moves and ink within the nozzle
is ejected out through the opening.
