1. A method for calibrating a thermistor in a liquid drop ejector, the method comprising:

  • first measuring a first resistance of the thermistor of the liquid drop ejector at a first temperature;

    heating the thermistor;

    second measuring a transient resistance response of the thermistor through a range of varying temperatures;

    generating a plot of thermistor resistance against thermistor temperature based on the first and second measuring; and

    ,calculating an operating temperature resistance based on the plot.
