FIELD: instrumentation.SUBSTANCE: proposed device comprises central temperature gage and end part temperature gage secured at appropriate ends of fixing roller. This is done to define fixing roller central and end temperatures to see if the difference between temperature gradients of said parts stays within the range of their permissible magnitudes. Besides, to check is central gradient temperatures are larger than threshold gradient temperature, or equal them. It is possible to define if there is the fault of fixing device, central or end temperature gages.EFFECT: possibility to define the conditions of fixing device and imaging device incorporating said above described device.20 cl, 10 dwg |
