Fuser film sleeve manufacturers tell you that the fuser components include pressure roller, paper exit sensor, heat roller, fuser lamp, thermistor, fuser thermostat, separation claws. Fuser film sleeve manufacturers tell you that fixing is the process of putting the photosensitive material after the stop of development into the fixing solution, and after a certain chemical treatment, the image formed by the development is fixed.

The Fuser film sleeve manufacturer tells you that the photosensitive material that has stopped developing contains a large amount of silver halide that has not reacted during development. Therefore, it is still invisible to light. The silver halide that has not reacted during development must be removed by fixing. In order to make the image formed by development completely fixed.
Pressure roller, the pressure roller is a sponge roller, which can ensure the amount of pressing between the fixing rollers. Fuser film sleeve manufacturers tell you that the paper is pressed against the fuser roller by spring pressure, thus effectively fusing the toner to the paper.
Exit sensor, the exit sensor detects whether the leading edge or trailing edge of the paper passes the pressure roller and heat roller, and it is also used to detect whether there is a paper jam in the fuser/exit unit.
The heat roller is heated by the heating and fixing lamp installed in the roller, thereby heating the paper, melting the toner on the paper, and the heat on the roller will fix the toner on the paper.
The fixing lamp and the fixing heating lamp are generally halogen lamps, which are used to heat the fixing heat roller. Fuser film sleeve manufacturers tell you that the fuser lamp is fixed inside the heat roller to heat it, and when the heat roller rotates, the fuser lamp does not rotate.
The thermistor, the thermistor used in the fixing part of the copier is a thermistor with a negative temperature coefficient, and the resistance of the resistance decreases with the increase of temperature. Fuser film sleeve manufacturers tell you that the motherboard uses a thermistor to detect the temperature of the fuser heat roller and keep it within a specific temperature range.
The temperature is between the lower temperature limit that causes poor fusing and the upper temperature limit that causes fusing ghosting. The Fuser film sleeve manufacturer tells you that when the temperature of the fixing roller is lower than the preset temperature, the thermistor will turn on the power of the fixing lamp; when the temperature is higher than the preset temperature, the thermistor will cut off the power of the fixing lamp.
