ABSTRACT:
An ink jet printhead which has a plurality of nozzles3and a chamber7corresponding to each nozzle respectively. A heater element10disposed in each bubble forming chamber7to heat printing fluid11to a temperature above its boiling point to form a vapour bubble12that causes the ejection of a drop16of the printing fluid through an ejection aperture5in each nozzle3. The heater element is a suspended beam mounted at its respective ends to laterally opposing portions of the chamber. A suspended beam heater element mounted to opposing sides of the chamber forms a symmetrical bubble. This provides better control of the pressure pulse generated which in turn gives a more predictable trajectory for the ejected drop.
