A method for cleaning printer fuser rollers

Fuser rollers can develop a band of baked-on toner which is difficult to remove because it is harder than the fuser's PTFE coating. I have developed a cleaning method which has worked well for me so far. First, wipe the roller with a swab or soft cloth and a few drops of isopropanol. Next, stick a piece of packing tape onto the roller where the toner has adhered and rub it so that it sticks well. Finally, pull off the tape in the direction of a tangent line to the curve of the roller so it 'snaps' off rather than peeling it off. It may take a few tries, but the toner should come off in large pieces. A blast of cold spray can help with stubborn deposits. It isn't necessary to remove the roller from the fuser with this method--just work in small sections and turn the roller a bit more each time.
