HOW WOULD I RESET ANY CODE IN MY BIZHUB 420

This is a under temp code from Temp sensor 1 (TEMS/1). You should check your thermistor, clean it. Then you have to reset the code.
To reset: Go to DipSW 3-1 and set to 0.
You may have a bad sensor or heat lamp.
Hope this helps.

C-1102 is a tray lift motor failure. Your copier is equipped with a FS-511 finisher. The trays on the left side (where the paper comes out) is being blocked when its trying to move up/down. Ensure the are no obstructions an restart your machine.

Have a tech come out admin password can change many things. should be done by a tech

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.
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 the 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.

Have the fusing unit replaced. One attempt only to reset if you continue to get the code the machine can catch on fire! That would ruin a perfectly good day. If the code comes back after this procedure have a qualified Konicaminolta Service tech look at it.. First power off the machine with both switches. Wait 10 second turn on the switch inside the machine then holding down the Utility/Counter button turn on the second power switch on the control panel keep the utility /Counter button down until you get Trouble reset then touch get a OK then power off the machine wait ten seconds power back on.

4701=index sensor abnormality, turn off main switch turn back on.

I had an older Minolta a couple of years ago. I'll try adapting what worked for it to this machine. Hopefully this will work.

Press the "utility" button. Then hit "admin settings". Enter a password of 12345678. Then hit "user authentication" and put in "off". Hit panel reset from the main menu.

Again, I'm not entirely sure this will work for the 420 but its worth a shot. Good luck!
