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.
Claims8
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;
- an optical scanner configured to scan the temperature indicator to detect the optical property of the temperature indicator, the optical scanner being configured to generate a signal corresponding to a temperature of the surface of the media heater with reference to the detected optical property;
- and
- a media heater controller configured to receive the signal generated by the optical scanner, calculate a temperature profile of the surface of the media heater with reference to the signal, and control the temperature at the surface of the media heater with reference to the calculated temperature profile.
