Abstract
The present invention includes as one embodiment a method of ejecting a fluid onto a print media. The method includes providing an ejection head having a nozzle that is coupled to a temperature sensor and a memory device. The method further includes measuring an uncalibrated temperature of the ejection head with the temperature sensor, recalling a correction value from the memory device, applying the correction value to the uncalibrated temperature to generate a calibrated temperature, and ejecting fluid from the nozzle onto the print media when the calibrated temperature is within a predefined temperature range.
