ABSTRACT:
An inkjet printhead chip includes a substrate that defines a plurality of ink inlet channels. A drive circuitry layer is on the substrate. A plurality of nozzle arrangements is on the substrate. Each nozzle arrangement includes nozzle chamber walls and a roof on the substrate to define a nozzle chamber opening into a respective ink inlet channel, with the roof defining an ink ejection port opening into the nozzle chamber. An ink ejection member is in the nozzle chamber. The ink ejection member is displaceable with respect to the substrate to eject ink from the ink ejection port. An actuator is connected to the ink ejection member and to the drive circuitry layer. The actuator is displaceable upon receipt of an electrical signal from the drive circuitry layer to displace the ink ejection member and thus eject ink from the ink ejection port. A lever mechanism interconnects the ink ejection member and the actuator. The lever mechanism is pivotal with respect to the substrate so that reciprocal movement of the actuator is imparted to the ink ejection member.
