Provided is a micro-electromechanical nozzle arrangement for a printhead integrated circuit. The arrangement includes a nozzle chamber defined in a substrate with a roof that defines an ink ejection port. The nozzle arrangement further includes a paddle located inside the chamber below the ink ejection port, said paddle operatively ejecting ink from the chamber through the port. Also included is an actuator arm having a fixed end fixed to the substrate and a working end that is displaceable towards and away from the substrate upon receipt of a drive signal in the form of a current pulse emanating from a drive circuitry layer on the substrate. The arrangement further has a motion transmitting structure interconnecting the working end of the actuator arm and a proximal end of the paddle.
