ABSTRACT:
An inkjet printhead is provided having ink chambers, ink ejection ports defined in the chambers, and cantilevered ejection arms positioned in the chambers. Each arm has a displacement area that acts on ink in the respective chamber through cantilevered movement of the arm to eject ink via the respective port. Each displacement area is greater than half an area of the respective port but less than twice the area of that port.
