ABSTRACT:
Provided is an inkjet printhead for a printer, the printhead having a plurality of micro-electromechanical nozzle assemblies. Each nozzle assembly includes a substrate defining an ink inlet channel and an arm fast with a thermal actuator itself fast with said substrate via an anchor arrangement. Each nozzle assembly also includes a nozzle on the substrate defining an ink aperture over the ink inlet channel, with a nozzle rim of the nozzle being inwardly displaceable by the actuator to eject ink from the aperture. The nozzle has a skirt portion and an inwardly directed lip that forms a fluidic seal in a complementary manner between the ink aperture and the thermal actuator.
