Malfunction c3451 detected for bizhub 250 konica minolta

Try this It could do the trick for you.

The error code c3451 refers to a copier warm up error; the machine had not reached the correct temp within a specific time.
I bet it happened when you first switched on one morning.
Easy to reset and fault usually goes away.

To Reset switch machine off using the switch inside the front door, not the one on the control panel.
Whilst holding the UTILITY key down on the control panel switch the machine back on keeping the UTILITY key held down. Eventually a Trouble reset key will be displayed in the LCD screen, touch this, OK will be displayed then power the machine off and then back on.

This will reset the error code, if the code reoccurs then there will be a problem with the fuser unit in the machine, and this will require replacing.

Malfunction(Code 3451) of Bizhub C252

This is a fuser heat error. The fuser unit is located in the area where the paper exits the machine. It heats up and "fuses" the toner onto the paper. The error code means that it did not heat up properly. This means you will most likely need a service person to come out and diagnose the problem.
You can try to reset the error but I doubt it will help.
Turn off the MAIN power switch (not the one on the control panel)
Now hold down the utility key while turning on the main switch and continue holding the utility key for at least 10 seconds. You should see a screen come up with nothing but "trouble reset"
Touch trouble reset and you should see a small "ok" come on. Then turn off then on the main switch again.
Good Luck and Thank You for using Fixya.

Konica Minolta Error code C-D351 on a Bizhub C250


I have come across this kind of problem.

Is your BizHub on the network? If yes, please switch it off completely, and take the Ethernet cable out of the BizHub.

Wait for atleast 30 seconds and reconnect the cable. Now start the printer again and see if the error message goes away.

Hope this helps!

It is a fuser error.

Try resetting. To reset a Rank A error follow these steps:

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.
If the error recurrs then do the following:
1 Check the Fusing Unit for correct installation (whether it is secured in position).
2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary.
3 Change Fusing Unit
4 Change PWB-M
5 Change PU1

Konica Milota Bizhub C250 Error Message

First power off the printer completely. Then power it back on while holding the UTILITY/COUNTER button. You will see the minolta logo, then you will see a troubleshoot reset button. Press it, you will see an OK result. Power off the printer again, then power it back on without holding the button and everything should work.
