1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble 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:

Malfunction c3451 detected for bizhub 250 konica minolta
Hi,
Hi,
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.

Malware functions eror cod c3451
C3451 is a Warm Up Failure. The fusing unit uses heat a pressure to "fix" the toner onto the paper. This code means that this unit is not heating up properly. You will need a service person to diagnose which part has failed and effect repairs to resolve this code.
Here is the info from the service manual:
The Fusing Roller Thermistor does not detect
the required temperature within 30 sec. after a
warmup cycle has begun; therefore, the copier
does not complete the warm-up cycle.
• The temperature of the Fusing Rollers does not
reach the required level even after the set period
of time has elapsed during a warm-up cycle.
