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.

A temperature monitoring system for a media heater of an imaging device, the temperature monitoring system comprising:
- a temperature indicator overlying a surface of a media heater of an imaging device, the temperature indicator being configured to vary an optical property in response to changes in temperature at the surface of the media heater;
- and
- an optical scanner for scanning the temperature indicator to detect the optical quality, the optical scanner being configured to generate a signal corresponding to the detected optical property.
A method of monitoring a temperature of a media heater of an imaging device, the method comprising:
- detecting an optical property of a temperature indicator overlying a surface of a media heater of an imaging device, the temperature indicator being configured to vary an optical property in response to changes in temperature at the surface of the media heater;
- and
- generating a signal corresponding to the detected optical property.
A media heating system for an imaging device, the media heating system comprising:
- a media heater for heating a recording medium in an imaging device;
- a temperature indicator overlying a surface of the media heater, the temperature indicator being configured to vary an optical property in response to changes in temperature at the surface of the media heater;
- an optical scanner for scanning the temperature indicator to detect the optical quality, the optical scanner being configured to generate a signal corresponding to the detected optical property;
- and
- a media heater controller for receiving the signal from the optical scanner and for controlling the temperature at the surface of the media heater in accordance with the signal.
