Zusammenfassung:	PROBLEM TO BE SOLVED: To maintain an ink temperature in an ink jet printer using a phase change ink.SOLUTION: An inkjet printhead includes multiple inkjets arranged in a jetstack of the printhead. Each inkjet includes an inkjet nozzle and an actuator that controllably dispense drops of a phase change ink melted by heat according to a predetermined pattern. One or more heaters are arranged along the jetstack to heat the phase change ink to a temperature above the melting point of the ink. The printhead includes at least one pulsating heat pipe 101 thermally coupled to the jetstack.
