Toner building up on the fuser can be caused by many different factors. The fuser not getting hot enough, the print media being used, aftermarket toner and even power supplies that are failing. Once the toner does start to accumulate on the fuser rollers it can become hard to remove. You might start to see some print quality problems such as ghosting, smearing or some type of repetitive defect. 

Some  printers have a cleaning page feature built in to the printer that you can set to run a cleaning page after a certain amount of pages get printed.  What this does in most printers is print a page with a full horizontal/diagonal bar on the page. Then the printed sheet is run through the printer again usually through tray 1 with the printed side up. The fuser is heated to a higher temperature and then the theory is the toner will then stick to the band of toner on the cleaning sheet. This procedure can be run more than once if you see that the toner is coming off on the cleaning sheet, but print a new cleaning sheet each time. Sometimes this will not take all of the toner off of the fuser. If you are in a bind and do not have a toner at the time. You can use acetone to clean the upper sleeve or metal roller. I don’t know many techs that carry acetone in their tool bags. Alcohol can be used but it will take twice as long to clean the toner off and if really caked on alcohol will not work.

Whatever is causing this problem will still need to be addressed. Start with easiest things first, such as the media supply then the toner cartridge. The problem might not occur immediately so it might take time to figure out what is the cause.
