C454e with error code C3425, preform trouble reset after replacing the fuser unit and the code continues to return. According to the service manual relevant parts are fuser, DC Power Supply and PRCB. Replaced the DC Power Supply, could this really be the PRCB? The customer was running copies and noticed the toner was not fusing, it would wipe right off. Then it gave the trouble code...any thoughts?
there is a board that controls the fuser replace it. DCPU
I replaced the fuser, DC power supply and the PRCB...C3425 remains. Any thoughts? Initially the customer reported toner was smudging off the paper (not fusing) and then the machine threw an fuser error. Replaced the fuser, reset code and then the C3425 began.
Can you run the machine at all? If you run it is the fuser warm? Maybe the coil unit, although I don't think I've ever replaced one on any machine.
The machine does not run at all. After resetting the trouble code and rebooting the machine the code comes up within the first few seconds of warm up.
replace the coil now that you did everything else
Also check and clean the Heating Roller Temperature Sensor that's located under the coil.Originally Posted by copierwhisper
he did replace the fuser
The heat roller temp sensor isn't located in the fuser.
If the problem is coil, how to fix it, there is another way to fix the coil
? All we must change it. Thx once again
