How to fix Error Code C3901 on a Minolta Bizhub 420 copier

FIRST, if this code comes back. Have a technician look at it DO NOT CONTINUE TO RESET the code!!!! AS this is for the Hot Part called the FUSER. It can catch on fire! And that will ruin a perfectly good day!!!!
1. Turn OFF the main power switch. Inside machine, leave sub-power switch on (Right side of control panel)
2. Turn main power switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and then it has been reset.
5. After turning off the main power switch, turn it on again more than 10 seconds after and check if the machine starts correctly.
