摘要： A method of detecting a missing nozzle and an ink jet print head using the same, that can detect a missing nozzle immediately with a simple process when the missing nozzle is generated. The method of detecting a missing nozzle used in an ink jet print head provided with plural chambers in which an ink is filled, plural heaters corresponding to the chambers, and plural nozzles corresponding to the heaters, can include detecting a temperature of each of the nozzles, and when the detected temperature deviates from a predetermined temperature range, determining that the nozzle is a missing nozzle.
