Abstract:
1. A system for cooling a heated image receiving member comprising: a first temperature sensor for sensing a temperature in a first portion of an image receiving member; a second temperature sensor for sensing a temperature in a second portion of an image receiving member; a first fan for directing air from the first portion of the image receiving member to the second portion of the image receiving member; a second fan for directing air from the second portion of the image receiving member to the first portion of the image receiving member; a controller configured to activate the first fan in response to detection of the first temperature sensor sensing a temperature greater than a temperature threshold and the temperature sensed by the second temperature sensor being less than the temperature threshold, to activate the second fan in response to detection of the second temperature sensor sensing a temperature greater than the temperature threshold and the temperature sensed by the first temperature sensor being less than the temperature threshold, and to activate only one of the first and the second fans in response to detection of the first temperature sensor sensing a temperature greater than the temperature threshold and the second temperature sensor sensing a temperature greater than the temperature threshold.
