How To Clean A Upper Fuser Roller

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 better not to use harsh chemicals like acetone or trichloroethane, pay attention when you clean a fuser film sleeve, as it's very fragile and easily demaged, insert the sleeve into a support, wipe away the old grease from the heating element and apply the new high temperature grease, if you don’t have the grease, remain the old grease.
