Abstract
A temperature monitoring system for a media heater of an imaging device comprises a temperature indicator overlying a surface of a media heater of an imaging device. The temperature indicator is configured to vary an optical property in response to changes in temperature at the surface of the media heater. The system includes an optical scanner for scanning the temperature indicator to detect the optical quality. The optical scanner is configured to generate a signal corresponding to the detected optical property.
