Abstract
Provided is an inkjet nozzle arrangement for an inkjet printhead. The arrangement includes a wafer substrate defining sidewalls and a roof portion to form an ink chamber, the roof portion further defining a nozzle aperture, as well as a heater element suspended inside the ink chamber for thermal expansion and subsequent ejection of ink from the chamber via the nozzle aperture. The arrangement also includes a nozzle rim defined about the aperture on the roof portion, said rim having an inner and an outer lip to facilitate ink drop misdirection during ink ejection to minimise cavitation corrosion of the heater element.
