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.

System and method for detecting a fire in a fixer unit of a printer or copier

In a printing or copying device which has one or several exchangeable part units with a modular assembly, the part unit to be identified has an identification device with a non-volatile memory for storing function-relevant operating data of the part unit, said operating data being allocated to operating states. The part unit also has a communication interface for detachably connecting the identification device to a process control device of the printing or copying device.
