Abstract
A thermal ink jet print device having a phase change material, a solid or fluid, disposed in heat exchange proximity to the thermal ink jet printhead to absorb printhead heat energy by changing physical state at a printhead temperature below that at which unacceptable printing takes place and at a rate commensurate with the rate of heat energy input.
