ABSTRACT:
Provided is a printhead integrated circuit defining an external surface having a number of ink ejection ports operatively directed at a printing medium. The surface includes a plurality of petal formations radially positioned about each ink ejection port, and a plurality of actuators, each located behind a petal formation distal from said port. The surface also includes a plurality of heater structures each connected to an actuator, so that heating of the structures via an electrical current produces expansion in said actuators which urges the formations into a chamber below the surface.
