摘要

A method for determining the of a heat source (21) of a fixing station power demand of heat to be applied to the fixing of toner images on a printing material (11) in the case of an electrographic pressure - or copying device,– in the case of which a) (10) of the printing material (11) of a heat radiation (12) is exposed to, wherein, during a measuring process a region of the printing material (11) of the heat radiation (12) is exposed and wherein the switching time of the) (10) is shorter than the cooling time of the printing material (10) is,– in the case of which the in the irradiated region from the printing material (11) (13) heat given off during the irradiation by the) (10) by a temperature sensor (14) is measured and in which a from the temperature sensor (14) is determined by the temperature curve,– in the case of the with an evaluation circuit (15) from the temperature curve of the required heating output of the printing material (11) is determined.
