Title: Method for regulating ink droplet drive control in ink jet print head

Abstract: A drive regulation method for an ink jet print head, wherein a plurality of ejection signals are prepared for driving an ink jet print head in various states. The ink jet print head is controlled to eject ink based on each of the selected signals. The ejection signal that achieves the most stable ejection aim from each of the nozzles is used as the ejection signal for that ink jet print head. In order to determine which of the ejection signals achieves the best result, dot arrays are printed on a recording medium for each ejection signal and the recorded dot arrays are examined for degree of unevenness. The ejection signal that achieves the most even dot array is selected. The ejection signals selected for each ink jet print head are stored in a memory device.
