A method and apparatus for correcting deviation of a temperature sensor placed in a header having a plurality of nozzles in an inkjet printer is provided. The deviation correcting method includes spraying ink through the nozzles a predetermined number of times, measuring a temperature of the temperature sensor corresponding to the number of sprayed times, measuring a voltage output from the temperature sensor, and determining a correction value of the temperature sensor using the measured temperature and the output voltage. According to the method and apparatus, it is possible to correct a large amount of deviation of a thermistor in a header without using an additional element, that is, an ambient sensor. Therefore, since an expensive ambient sensor is not used, costs can be reduced and a printer circuit configuration is simplified.
