When cleaning the Upper fuser roller, wipe it carefully with absorbent cotton dipped in absolute alcohol. But do not wipe the heating roller too hard, and do not scrape it with a blade or sharp object, so as not to damage the fixing heating roller. The wipe of the rubber roller can be simpler, just wipe the surface clean.

The upper fuser roller may be covered with a layer of toner after long-term use. Generally speaking, the surface of the heating roller should be very clean, if it is dirty, it will affect the printing effect. If the printed sample has black blocks, black stripes, and the toner of the graphic and text is stuck to other places, it means that the surface of the heat roller has been damaged or damaged. If it is slight, it can be used after cleaning (but it is not suitable for sulfuric acid paper) ), if serious, only replace the heating roller.
The rubber roller paired with the heating roller will also be stuck with waste powder after long-term use. The Upper fuser roller manufacturer tells you that generally it will not affect the output effect if it is slight, but if it is serious, it will make the back of the output sample dirty.
Copiers of general models have two upper and lower rollers. The upper fuser roller is mostly hollow inside and has a heating lamp for heating. The high-quality fuser roller tube is mostly made of pure aluminum, and the tube wall is thinner, which ensures the effective conduction of heat. The lower roller is commonly known as "rubber roller", with a metal component in the middle and a thicker, high-temperature-resistant silicone rubber on the outside.
