ABSTRACT:
An ink jet printhead nozzle arrangement having an ink chamber formed in a wafer substrate and one wall of said chamber having at least one flexible portion. The ink ejection port is formed substantially centrally on the wall with a rim surrounding it. The wall is adapted to move independently of said rim. Rib elements are located on the outer surface of the wall to restrict the wall movement such that upon actuation of the at least one flexible portion of the wall, the wall is forced to move into said ink chamber, forcing ink therein out through the said ejection port.
