ABSTRACT:
Provided is a printhead having a plurality of nozzle arrangements. Each arrangement includes a substrate which defines an ink inlet aperture with a wall portion bounding the ink inlet aperture and a crown portion defining a nozzle opening. Each arrangement also includes a skirt portion depending from the crown portion to form part of a peripheral wall of the nozzle assembly. The crown and skirt portions are displaceable with respect to the wall portion towards the substrate to alter a volume of a nozzle chamber defined by the wall, crown and skirt portions such that when the volume is altered, ink is ejected from the nozzle opening. Each arrangement also includes a thermal actuator that interconnects the crown and skirt portions with the substrate, the actuator for displacing the crown and skirt portions. The wall portion and skirt portion are configured to define a fluidic seal to inhibit the egress of ink during such displacement.
