    • In a fixer unit system and method to detect a fire in a fixer unit of an electrographic image generation device, at least one portion of a fixer region of the fixing unit is monitored with a photoelectric sensor arranged adjacent to a substrate material having a toner image to be fixed, at least one portion of radiation generated by at least one heat radiator of the fixer unit is not detected by the photoelectric sensor by not passing said at least one portion of the radiation generated by the at least one heat radiator through to the photoelectric sensor by use of an optical filter associated with the photoelectric sensor. An error signal is output when a fire in the fixer region is detected with the photoelectric sensor.
    • 在用于检测电子照相图像产生装置的定影单元中的火灾的定影单元系统和方法中,用邻近具有调色剂图像的基底材料布置的光电传感器监测定影单元的定影区域的至少一部分 为了固定,由光电传感器不检测由固定器单元的至少一个散热器产生的辐射的至少一部分,不将至少一个散热器产生的辐射的至少一部分通过至 光电传感器通过使用与光电传感器相关的滤光片。 当用光电传感器检测定影器区域的火灾时,输出误差信号。
