Abstract
A fuser heater within a printing device includes a substrate with conductive traces and a resistive trace having a first end and a second end. The resistive trace is connected to the conductive traces at each of the first end and the second end and forms an electrical connection between the conductive traces and the resistive trace. A first strip is printed on the substrate using a first metal ink. A second strip is printed on the substrate using a second metal ink. The second strip is in contact with the first strip. The first metal ink is different from the second metal ink. The first strip and the second strip form a thermocouple. The thermocouple is operatively attached to the conductive traces. A controller operatively attached to the thermocouple controls the temperature of the fuser heater.
