PROBLEM TO BE SOLVED: To provide a cleaning method for a fluid jetting apparatus by which the generation of a multiple nozzle slipping off when a printing process is performed after being left to stand for long hours can be prevented from occurring, and to provide the fluid jetting apparatus. SOLUTION: This cleaning method is used for the fluid jetting apparatus equipped with a jetting head 3 having a plurality of jetting nozzles 47 which jet a fluid to a target, and a common fluid chamber which feeds the fluid to the jetting nozzles 47. The cleaning method has a preliminary discharging step, a detection step, a parameter determining step, and a cleaning step. In this case, in the preliminary discharging step, a preliminary discharging motion in which the fluid is discharged from the jetting nozzles 47 is performed. In the detection step, the jetting situation of the fluid in each jetting nozzle 47 after the completion of the preliminary discharging step is detected. In the parameter determining step, a processing parameter at the time of the cleaning of the jetting head 3 is determined depending on the inspection result. In the cleaning step, the cleaning is performed to the jetting head 3 conforming to the processing parameter. In the preliminary discharging step, the fluid which is equivalent at least to the volume of the common fluid chamber is jetted. COPYRIGHT: (C)2009,JPO&INPIT |
