Hi Stephen,
This error code c3451 refers to a copier warm up error; the machine had not reached the correct temp within a specific time.
Try resetting it by switching 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 hopefully reset the error code. However, if the code reoccurs then there will be a problem with the fuser unit in the machine, and this will require replacing
Sir/Mam,
On the right side of the machine just below the scanner section (The part with the big glass) is a cover next to where you connect the Ethernet cable. Remove the cover, with the machine on use a small screw driver and gently depress the small black switch. The machine is going to go thru some screens when you see the screen with the copiers on it to the left on the screen in the middle you will see a "." when that is displayed press 3. The code will come back but now press the Utility/Counter button, you should see a button that says Maintenance Mode press that, see Trouble Reset press that and the machine will again will go thru warm up procedure, you will see the "." DO Nothing! The machine should go to "Ready to Copy" if the code comes back. Have a technician look at it DO NOT CONTINUE TO RESET the code is for the Hot Part called the FUSER. It can catch on fire! And that will ruin a perfectly good day!!!!
