ABSTRACT:
A nozzle arrangement for a printhead integrated circuit is disclosed. The arrangement includes an ink chamber having an ink ejection port, an ink ejecting member angularly displaceable within the ink chamber, a thermal bend actuator reciprocally displaceable upon receipt of a drive signal, a motion transmitting structure comprising an effort formation, a lever arm formation and a load formation, the lever arm formation being interposed between the effort formation and the load formation, the effort formation being connected to the thermal bend actuator and the ink election member being connected to the load formation, and a resiliently deformable sealing structure, interposed between a substrate upon which the nozzle arrangement is formed and the lever arm formation, to permit pivotal movement of the lever arm formation with respect to the substrate. Reciprocal displacement of the thermal bend actuator is converted into reciprocal displacement of the ink ejecting member through the motion transmitting structure, thereby ejecting ink that is in the ink chamber from the ink ejection port.
