ABSTRACT:
A printhead integrated circuit assembly includes a substrate having a plurality of micro-electromechanical nozzle arrangements formed thereon, each micro-electromechanical nozzle arrangement including a nozzle chamber defined by a crown portion, a skirt portion, and a wall portion; a lever arm included with the micro-electromechanical nozzle arrangement, the lever arm connected at one end to the crown and skirt portions, and at another end to an actuator, the lever arm adapted to move the crown and skirt portions with respect to the wall portion; drive circuitry for supplying a current to the actuator, the current for heating a portion of the actuator to bend the actuator through thermal expansion; containment walls extending from the substrate to surround each micro-electromechanical nozzle arrangement; and a nozzle guard mounted on the containment walls to individually enclose therein, together with the containment walls, each micro-electromechanical nozzle arrangement, the nozzle guard defining therethrough a plurality of apertures aligned with nozzle openings of respective micro-electromechanical nozzle arrangements.
