Inkjet printer utilizing low energy titanium nitride heater elements

摘要

An inkjet printer includes an array of nozzles extending substantially a width of a print media fed through the inkjet printer; and a plurality of heater elements each corresponding to a nozzle, each heater element being formed substantially of titanium nitride and suspended in direct contact with a bubble forming liquid with the bubble forming liquid surrounding the heater element. Each heater element has a mass of less than 10 nanograms, and sized to heat the bubble forming liquid above a boiling point thereof upon application of 200 nJ or less of energy to each heater element.
