More Information
Summary:The invention relates to a method of detecting a missing nozzle and an ink jet print head using the same can detect a missing nozzle (31) immediately with a simple process when the missing nozzle is generated. One method of detecting a missing nozzle used in an ink jet print head provided with plural chambers (21a), plural heaters (11) corresponding to the chambers, and plural nozzles corresponding to the heaters can include detecting a temperature of each of the chambers, and when the detected temperature deviates from a predetermined temperature range, determining that a nozzle corresponding to the chamber is a missing nozzle.
