ABSTRACT:
A method for operating a thermal ink jet printer including a printhead having a sample resistor and ink firing heater resistors responsive to pulses provided to the printhead. The resistance of a sample resistor is read and the pad to pad resistance of the printhead is determined. The operating energy of the printhead is determined from a look-up table and the target power is determined from the target pulse width. The power supply voltage is determined from the target power and the power supply voltage is set. The operating power is determined and the operating pulse width is set based on the operating power and target energy.
