Abstract
A micro-electromechanical ink ejection mechanism for an inkjet printhead includes a substrate. A nozzle chamber structure is arranged on the substrate and defines a nozzle chamber and an outlet in fluid communication with the nozzle chamber. An ink ejection member is suspended within the chamber and is displaceable towards and away from the outlet to eject ink from the outlet. The ink ejection member is capable of electro-magnetic actuation. An electro-magnetic actuator is configured to actuate the ink ejection member so that ink is ejected from the outlet.
