After clearing error stay at the machine to see if it comes to ready. The fuser assy can reach 139 degrees C.(Water boils @ 100C) The error can only be cleared through the service mode because a technician should inspect the fuser to verify there is nothing faulty that could possibly start a fire. If you enter the service mode & clear the error, power cycle the machine & during warm up the machine throws a code again- turn it off, unplug it & call a tech for fuser repair.

This Error code means that the fuser film is not reading the home postion. You will have to replace the fuser film or replace the fuser unit. Untill it is repaired you will not clear the code. Good Luck

Check the fuser unit and make sure its installed correctly.
