Patent ID: 8240804

Claim:
A printing apparatus comprising: a print head configured to eject ink, the print head being removably installed in the printing apparatus and having a temperature sensor and a memory holding information on a property of the temperature sensor; first sensing means for sensing a temperature of the print head using the temperature sensor; second sensing means for sensing an environmental temperature of the printing apparatus; acquisition means for acquiring information on the property of the temperature sensor from the memory, at a predetermined timing; and correction value acquisition means for acquiring a correction value to correct the temperature of the print head sensed by the first sensing means, by comparing the temperature of the print head sensed by the first sensing means with the environmental temperature sensed by the second sensing means, wherein the correction value acquisition means does not acquire the correction value if first information acquired by the acquisition means after the print head is installed is the same as second information acquired by the acquisition means before the print head is installed.
