Abstract
A nozzle arrangement is provided for an inkjet printhead. The nozzle arrangement includes a substrate assembly defining an ink inlet channel. A nozzle extends from the substrate assembly. The nozzle defines a nozzle chamber in fluid communication with the ink inlet channel and a ink ejection port in fluid communication with the chamber. A cantilevered actuator extends into the ink inlet chamber and terminates in a paddle at its free end that can cover the ink inlet channel. The actuator includes a heater element which can be activated to bend the actuator so that the paddle ejects ink in the nozzle chamber through the ink ejection port.
