Abstract
The present invention is an energy control system and method for an inkjet printer cartridge for controlling the droplet firing energy. One embodiment of the present invention includes calibrating an inkjet print cartridge having a printhead die divided into sections. This method includes selecting an operational range of the inkjet print cartridge, measuring the electrical characteristics of the electrical components over this operational range, calculating an optimal calibration value for the electrical characteristics of each section, and storing these optimal calibration values. In addition, the present invention allows operation of an inkjet printer having a print cartridge for determining optimal operating settings for the print cartridge. This method includes reading calibration values stored on the print cartridge, performing tests using the calibration values to determine optimal operating settings, adjusting settings on the print cartridge to the optimal operating settings, and storing the optimal operating settings in the printer.
