ABSTRACT:
An inkjet printhead having a plurality of ink ejection nozzles arranged on a substrate is provided. Each ink ejection nozzle comprises an ink chamber, an ink ejection port arranged on the ink chamber and a multiple-sectioned actuator arranged to be displaced relative to the ink chamber so as to cause ejection of ink from the ink ejection port. The actuator is displaced through actuation of at least one section. A first section of the actuator is pivotably mounted to the substrate and is arranged to contact the ink in the ink chamber. A second section of the actuator is coupled between the pivot point of the first section and an anchor arranged on the substrate. The anchor receives an actuation signal for actuating the second section which causes pivoting of the first section.
