There is no c3451 code in the bizhub 350 service manual.

You will need to replace the thermostat and the best solution is to call a technician.

the device takes too long to warmup. try switching off then back on when you see the message. if that does not work you will have to call for a technician i'm afraid. good luck

Hi there.

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.

Hope it did work for you.

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
