Abstract
A nozzle arrangement for an inkjet printhead, the nozzle arrangement including a substrate that incorporates drive circuitry and defines an ink chamber and an ink supply channel in fluid communication with the ink channel. A cover is fast with the substrate to cover the ink chamber. The cover defines an ink ejection port bounded by a nozzle rim through which ink can be ejected. The cover includes a plurality of actuators extending radially with respect to the rim. Each actuator has a free end located proximal to the rim, each actuator being configured so that, on receipt of a drive signal from the drive circuitry layer, its free end can move into the ink chamber to reduce a volume of the ink chamber and thereby eject ink within the ink chamber from the ink ejection port.
