ABSTRACT:
A printhead for an inkjet printer includes a wafer defining a plurality of nozzle chambers and a plurality of ink supply channel in fluid communication with the plurality of nozzle chambers for supplying the plurality of nozzle chambers with ink; an ink ejection port associated with each nozzle chamber; and a plurality of actuators associated with each nozzle chamber, the plurality of actuators each including a petal formation. A plurality of petal formations are arranged around an ink ejection port of each nozzle chamber to annularly surround the ink ejection port. Each actuator is operable to displace a respective petal formation into the nozzle chamber.
