ABSTRACT:
The invention provides for a nozzle arrangement for a printhead. The arrangement includes a wafer substrate defining a nozzle chamber, and a passivation layer formed on the substrate to define a roof wall and ink ejection port of the chamber. The arrangement also includes a paddle arranged in the chamber configured to operatively eject ink from the chamber via the ejection port, as well as a magnetic field generator fast with the wafer substrate, the generator configured to actuate the paddle to eject the ink.
