ABSTRACT:
There is disclosed an ink jet printhead which comprises a plurality of nozzles and one or more heater elements corresponding to each nozzle. Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through respective corresponding nozzle, to effect printing. Each heater element has a surface area to volume ratio greater than 4:1. This configuration ensures that heat is quickly transferred from the elements to the ink for efficient operation and minimal heating of the printhead substrate.
