ABSTRACT:
An inkjet printhead includes a nozzle chamber structure defining a nozzle chamber. The nozzle chamber structure further defines a pair of ink ejection nozzles and an ink supply channel in fluid communication with the nozzle chamber. A movable paddle is disposed within the nozzle chamber at a location between the ink ejection nozzles. An actuator is attached to the paddle and, upon actuation, can reciprocate the paddle toward and away from a first one of the ink ejection nozzles so that ink in the nozzle chamber can be ejected out through that first nozzle.
