摘要
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.
