Abstract
In a case where a temperature of the print head at a cap closing time is 35° C. or more and the cap closing time is less than six hours, a predetermined preliminary ejection is performed and the ejection number is set to 4000. That is, the predetermined preliminary ejection is, in a case where it is determined that the temperature of the print head at a cap closed time is lower than 35° C., performed by the ejection number larger than the ejection number of other preliminary ejection having the same cap closing time of six hours as that in the predetermined preliminary ejection. Therefore in a case where the temperature of the print head at a cap closing time is a predetermined relatively high temperature or more, the preliminary ejection more accurately reflecting the degree of the ink thickening in the print head at that time is performed.
