Inside the printer fuser assembly, there are two pieces of rollers, upper fuser roller or fuser roller, and lower fuser roller or pressure roller, the upper fuser roller is a high quality aluminium tube coated with teflon, with a heating element inside, sometimes, we can use a fuser film sleeve to instead of the upper fuser roller. The lower pressure roller is a soft rubber roller. The best way to clean a fuser roller is to use isopropyl alcohol if you haven't a specific cleaning fluid, just don't use rubbing alcohol, it may contain ingredients that can leave a residue on the fuser surface, you can also use a very light coat of silicon oil and a non linty rag. When the rollers are clean, dry them with another cloth. You can fully disassemble the roller before clean it, but it could be done with minimal removal just so the roller could be turned . The surface of the fuser roller is made of a teflon film that is easily damaged, so use only light pressure when cleaning, and...

Upper fuser roller is made of seamless alum alloy tube, its thickness is between 1-3mm, and there is a piece of printer heating element set in such a roller to generate heat, the surface of roller is covered with the fluorine resin film, which is usually called as fuser film sleeve. When the paper pass and is jammed in the fuser assembly , just don't pull t out heavily, as such an action may damage the surface coating of the fuser roller, and the damaged parts will fail to fuse the toner particles on the paper. If the paper comes out with some spots and residual toner, it may be due to that the surface of roller is damaged or scratched. When cleaning the surface, just use some cotton with alcohol to wipe gently off the stain on it, and remember that not to use blade to scrape it.

Upper fuser roller is a component to be used with fuser film sleeve that cover over it, and there is a piece of printer heating element set in such a roller to generate heat, when the paper pass through the roller, the heat is conducted by the fuser film sleeve to melt and fix the toner particle onto the paper. When the upper fuser roller working, such an action is also assisted by the lower pressure roller that is located under it to press the melted toner particle to attach tightly onto the paper. Upper fuser roller s manufactured by Zhonghui Technology can perform excellent thermal conduction for fusing process, and it also can release heat on the paper quickly, significantly improve the print efficiency, so that’s ideal options for refurbished fuser assembly manufacturers .

Upper fuser roller is also called as fuser roller , which is an important part to be used with fuser film sleeve that cover over it, and there is a piece of printer heating element set in such a roller to generate heat, when the paper pass through the roller, the heat is conducted by the fuser film sleeve to melt and fix the toner particle onto the paper. When the upper fuser roller working, such an action is also assisted by the lower pressure roller that is located under it to press the melted toner particle to attach tightly onto the paper.

Fuser roller has one or two heating elements (hologen lamps) inside to generate heat and transfer to the toner to melt and bond on the paper. Fuser film sleeve has a piece of ceramic bar to release heat and transfer via the fuser film sleeve to the toner. Fuser roller features high power consumption, slow preheating, but has long lifespan. Conversely, fuser film sleeve features low power consumption, fast preheating but wear resistance not good as fuser roller.

Speaking of laser printer parts, there as a pair of fuser roller to work through a combination of heat and pressure to bond the toner powder on the paper, the upper roller, sometimes called upper fuser roller, is covered around by fuser film sleeve which has excellent performance at thermal conduction and wear resistance, the function of fuser film is to transfer heat quickly from the upper fuser roller to the toner and melt it onto the paper sheet, and after bonding the toner, it also can release the heat quickly from the paper. For the original HP design fuser unit, it comes with plastic fuser film sleeve around the upper roller, the problem with the plastic film is that it’s not very durable material and tear within 30,000-50,000 pages of paper. So in these years, we’ve developed maintenance kit with new technologies, which the film surface comes with metallic coated and some material with electromagnetic induction, such type of item can excellent solution to last your ...
