ABSTRACT:
An inkjet printhead integrated circuit is provided. The integrated circuit comprises a plurality of nozzle arrangements, each nozzle arrangement comprising a nozzle chamber and an ink ejection member positioned in the nozzle chamber. The ink ejection member is displaceable with respect to the substrate. An actuator is connected to drive circuitry in the integrated circuit and is reciprocally displaceable upon receipt of an electrical signal. A lever mechanism interconnects the ink ejection member and the actuator. The lever mechanism comprises: (a) an effort end operatively connected to the actuator, the effort end being separate from the substrate; (b) a load end operatively connected to the ink ejection member; and (c) a fulcrum positioned between the effort end and the load end. The lever mechanism is pivotal with respect to the substrate about the fulcrum such that movement of the effort end due to the actuator imparts reciprocal movement to the load end. The reciprocal movement is, in turn, imparted to the ink ejection member.
