ABSTRACT:
A nozzle arrangement for an inkjet printer comprises a nozzle chamber; an ink supply channel for supplying ink to the nozzle chamber; a cover for covering the nozzle chamber, the cover defining an ink ejection port through which ink is ejected; a plurality of thermal bend actuators radially arranged around the ink ejection port; and a plurality of heater elements each corresponding to one of the plurality of thermal bend actuators. Each heater element is provided at an end of a corresponding thermal bend actuator opposite the ink ejection port.
