ABSTRACT:
There is disclosed an ink jet printhead which comprises a plurality of nozzles3and one or more heater elements10in a bubble forming chamber7corresponding to each nozzle3. Drive circuitry22corresponding to each of the nozzles for controlling the operation of the heater element10. Each heater element10is configured to heat a bubble forming liquid11in the printhead to a temperature above its boiling point to form a gas bubble12therein. The generation of the bubble12causes the ejection of a drop16of an ejectable liquid (such as ink) through an ejection aperture5in each nozzle3, to effect printing. Part of the drive circuitry22is disposed on one side of the bubble forming chamber7, and part of the circuitry22is formed on the opposing side of the bubble forming chamber7. Printheads manufactured in accordance with the present invention can have a relatively high nozzle density (nozzles per unit area).
