Solving Noise Issues After Replacing The New Fuser

Be certain that both sides of the fuser are firmly locked into the printer. Listen for the two locks to snap in when you install it. If the fuser is not secured, the printer may display a “50.3 FUSER ERROR” message or you may hear a grinding noise. In either of these cases, remove the fuser and reinstall it making sure that both sides are locked in place.
