ABSTRACT:
The invention relates to a nozzle arrangement for a printhead integrated circuit, the arrangement having walls defining a chamber and a roof with an ink ejection port defined in a substrate that incorporates drive circuitry. The arrangement further includes a motion transmitting structure formed on the substrate and having an effort formation, a lever arm formation and a load formation. The lever arm formation is interposed between the effort formation and the load formation. A resiliently deformable sealing structure is interposed between the lever arm formation and the substrate to permit pivotal movement of the lever arm formation with respect to the substrate. A thermal bend actuator is connected to the drive circuitry and is reciprocally displaceable with respect to the substrate on receipt of a signal from said drive circuitry. The actuator is connected to the effort formation so that reciprocal movement of the actuator towards and away from the substrate is converted into reciprocal angular displacement of the ejecting member via the motion-transmitting structure, to eject ink in the chamber from the ink ejection port.
