Abstract
A nozzle assembly is provided for ejecting ink. The nozzle assembly includes a substrate incorporating drive circuitry. An actuator support extends from the substrate. An actuator arm extends from the actuator support and includes a heater which is coupled to the drive circuitry. A nozzle extends from the substrate at a spaced apart location from the actuator support and the heater. The nozzle defines an ink chamber in fluid communication with: an ink supply, an ink ejection port in fluid communication with the nozzle chamber, and a slot through which the actuator arm extends and terminates in a free end within the ink chamber. Responsive to the heater receiving an electrical signal from the drive circuitry, the free end of the actuator arm is displaced in the ink chamber to eject ink contained therein through the ink ejection port.
