An inkjet printer and a head cleaning method for an inkjet printer reduce the time required for head cleaning while also reducing needless ink consumption. The control unit 30 of the printer 1 confirms if a timer AID flag, impact detection flag, startup process flag, AID hold flag, or cover closed flag is set before executing the cleaning process a first time. If any one of the flags is set, the possibility that there are numerous defective nozzles in the printer 1 is high, and a stronger or more intense cleaning process (CL1 or CL2) is executed. Whether cleaning process CL1 or CL2 executes is determined according to the number of defective nozzles detected in the first nozzle check. If no flag is set, the weakest cleaning process (CL0) is executed. |
