It's usually a teflon coating, like a cooking pan. Don't scrape on it with  
something hard, if the gunk doesn't come off you can heat it to operating  
temperature and then wipe it off (avoiding burns as much as possible).
There's usually a felt cleaning pad in contact with the fuser roller,  
check that out it is probably all gunked up and just spreading the stuff  
if much came off.

If you damage the teflon you get marks on each page.
