ABSTRACT:
Provided is a printhead having a plurality of nozzle arrangements. Each arrangement includes a wafer substrate defining a nozzle chamber, said chamber having a roof wall with an ink ejection port defined therein and an ink supply channel defined through the substrate for supplying the chamber with ink. Each arrangement also includes a magnetic paddle arranged within an electrical coil arrangement which is positioned about the inlet of the nozzle chamber such that the magnetic paddle ejects ink from the chamber via the ejection port when the coil arrangement receives electrical signals.
