PROBLEM TO BE SOLVED: To provide an ink jet printer in which clogging of an ink nozzle is detected at an appropriate time and recovery processing of a print head can be carried out efficiently depending on the detection results. SOLUTION: The cleaning controller 30 comprises a mechanism 40 for cleaning the nozzles of a print head 12, a mechanism 50 for detecting the ink state for the nozzles of a print head 12, and a control section 60 having a function 64 for making a decision whether the nozzle detection mechanism 50 is operated or not based on a specified criterion, a function 65 for operating the nozzle detection mechanism 50 based on the decision results, a function 66 for making a decision whether the cleaning mechanism 40 is operated or not based on the results obtained by the nozzle detection mechanism 50, and a function 67 for operating the cleaning mechanism 40 based on the decision results obtained by the cleaning decision function 66. |
