Develop ineo 250 printer error is c3451 - Office Equipment & Supplies

SOURCE: error c3451

First ignore the revious solution, it is not even close. 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 swiched 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 this helps

• 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.

You may have a bad fuser section. Another reset method is a small button located on the right side of the machine under on the scanner section. Locate your network port, then to the left of the port is a small cover that can be removed, behind that cover on the left is a small black button, use a paper clip or ball point pen and press the button, this will do a machine reset. When the operation panel abort starts to load hit the number 3 button, you should see a small back circle in the top right of the operation panel. This will give you the option to do a trouble reset.
If this does not work you will need a technician to come out and replace the fuser section, make sure they bring one with them so they don't have to reschedule and come back.

SOURCE: How much is a fuser unit for a bizhub 250? I got a

around 250-280 $ (include shipping) but you may need a technician to clear counters, reset error code, and install and test the new fuser. If you want to do it by yourself, may be time consuming.....
