Abstract:
A temperature detection circuit acquires first temperature data detected by a temperature sensor corresponding to a heater of a recording head in a state in which no electric current is flowed into the heater, and second temperature data for the heater in a state in which an electric current is flowed into the heater. Correction data for correcting the temperature data detected by the temperature sensor is obtained based on the first and second temperature data. The temperature data detected by the temperature sensor is corrected based on the correction data.
