  • Publication number: 20190176467
    Abstract: An object of the present invention is to quickly correct a temperature sensor for an ejection head by, both efficiently and in a brief time, estimating a detected temperature of the temperature sensor for the ejection head in a case where the temperature of the ejection head of liquid becomes sufficiently close to an environment temperature. The temperature of a print head 1 is detected by a diode sensor 17 and the environment temperature is detected by a thermistor 10. Based on a change in the detected temperature of the diode sensor 17 at the time of filling of ink for the print head 1, the detected temperature of the diode sensor 17 in a case where the temperature of the print head 1 becomes close to the environment temperature is estimated as an estimated detected temperature. Based on a difference between the estimated detected temperature and the environment temperature, a correction value of the detected temperature of the diode sensor 17 is set.
