  • Safety device for fixing heater
    Patent number: 4801974
    Abstract: Method and apparatus are provided for minimizing delay in the operation of a safety device in a device for thermally fixing an image to a paper medium. A safety device, such as a thermostat, is set to deactivate a heater unit if the temperature of the heater unit exceeds a first temperature value. If the temperature of the thermal unit exceeds a second temperature value lower than the first temperature value, a heat exhausting device, such as a fan, is turned off. Shutting off the heat exhausting device stops cooling of the heater, thus decreasing the time elapsed before the safety device can detect the first temperature value.
