Abstract

The resistance of a thermal print head's heating element typically changes with temperature. This property is exploited to estimate the temperature of the element. The proposed method employs a model for the temperature rise when power is applied to the element in conjunction with a model for mapping the resistance to temperature. The parameters of the model are learned from the resistance measurements using a maximum likelihood estimator. An analytical expression is obtained for the bias in the estimated parameters. Results for synthetic and real data show that the proposed methods estimate the resistance-temperature mapping with a high degree of accuracy.
