if the lamps are fine and the thermal fuses are fine it must be reset by entering the service program mode on the machiene--- cancel 1 0 7 stop {held in for a few seconds} then 5 # then 810 # then 1 # turn the machiene off then back on while the front cover is open close the front cover for about 5 seconds then open it again see if the fusing unit is warmer if it is the problem is solved! if you have any problems... you can e-mail me at cmpelser@yahoo.com OR sbdsolutions@yahoo.com
