Temperature sequence determining method for processing medium e.g. fixing roll, in electrographic printing device, involves determining temperature value over breadth using measured values by correlation of target-value to output-value

摘要

The method involves heating a processing medium, and measuring a temperature sequence over the breadth of the medium by a reference sensor arrangement (RS) having temperature sensors. One of the sensors is used as reference temperature sensor and whose measured value is used as an output-reference measuring value. The temperature of the medium is measured as a target-reference measuring value by a target-temperature sensor. The temperature value over the breadth is determined using measured values of the temperature sensors by a correlation of the target-value to the output-value.
