  • System for printhead pixel heat compensation
    Patent number: 6249299
    Abstract: A thermal imaging system for compensating for the temperature dependent changes in thermal elements of a thermal printhead is disclosed. Specifically, the thermal imaging system generates a temperature or energy dependent profile of the resistances of each thermal element which makes up the thermal printhead. Based upon this profile, the imaging system estimates the resistances of thermal elements based upon a pixel density to be transferred to media. Based upon the estimated resistances, the imaging system adjusts the amount of energy to be applied to particular thermal elements for transferring a pixel having a density which more closely approximates the density of a corresponding pixel in a desired image.
