ABSTRACT:
An inkjet printhead is provided having a plurality of ink ejection nozzles. Each nozzle has a substrate incorporating circuitry for supplying an electrical current and a channel for supplying ink, a chamber on the substrate in fluid communication with the channel, an aperture in fluid communication with the chamber, a micro-electromechanical actuator on the substrate electrically connected to the circuitry to be displaced on receipt of the electrical current thereby ejecting ink from the aperture, and an enclosure on the substrate enclosing the micro-electromechanical actuator.
