Abstract
A method for use with an ink jet printhead having a plurality of nozzles, each of the plurality of nozzles having associated therewith a respective heating element, includes printing with the plurality of nozzles a test pattern while varying an energy of a respective heater pulse used to energize each respective heating element at each of a plurality of printhead carrier positions; scanning the test pattern with a reflectance sensor to generate reflectance data associated with the energy of the respective heater pulse used to energize each respective heating element at each of the plurality of printhead carrier positions; and determining an optimal non-nucleating heater pulse for use with the ink jet printhead based on the reflectance data.
