摘要： PROBLEM TO BE SOLVED: To accurately predict and determine a service life of a recording head by obtaining variation of driving conditions of the recording head, in an inkjet recording device.SOLUTION: A difference between a re-measured optimum driving condition and an initial optimum driving condition of the recording head that is used is calculated (S406). Next, it is determined whether or not the difference is equal to or greater than a predetermined threshold value (S407). When the difference is equal to or greater than the threshold value, it is determined that a durable life of the recording head has reached an end, replacement of the recording head is prompted and this processing is ended. A variation amount of the optimum driving condition is obtained in advance when the service life of the recording head ends, and the varying amount is set to the predetermined threshold value. By a determination based on the threshold value, the service life of the recording head is determined and predicted. Thus, the service life of the recording head is accurately predicted and determined.
