That error says that you have the wrong fuser in the printer.
Why did you change the previous fuser?
The part number should be RM1-1043-000CN.
If you installed the correct fuser, then you should be thinking about changing the DC Controller.

I'm not real sure but I do know the the fuser area contains heat sensors. If the fuser temp is higher than it should be, you will get over-temp errors.

Get the printer serviced. It very well could be a motherboard failure or a fuser control card.

This 59.4 error is a fuser error. Which means it could either be the fuser is faulty, or the fuser motor. I would suggest calling HP support if your printer is under warranty, they should send you a replacement fuser.

The fuser unit will need to be replaced. It's possible that the heat lamp or thermostat of the fuser has failed, but getting those individual items could be difficult. The fuser unit should still be available from a Samsung repair center. Search on line for your nearest authorized dealer. You will continue to be able to send regardless of the fuser.

Power off the printer for 15 minutes and power back on again. If that fixes the problem then OK.
If not then go into maintenance mode -
Press and hold the menu/set key while turning on the machine. Wait until it comes completely up before releasing. It should say Maintenance in the display.

If not press function,*,2,8,6,4 within two seconds. It should say maintenance in the display. Or on some machines Menu,*,2,8,6,4 within 2 seconds.

Once you get it into maintenance hit 91 to do a parameter reset and than 99 to get out of maintenance.

If this corrects the problem then OK but you may have a failing thermister in the fuser.
If the problem happens again then change the thermister.

If the reset does not work then either the thermister or the fuser lamp has failed. In rare cases there is a poor connection with the cables to the fuser.

You will have to reset the parameter again after replacing the fuser if you need to replace the fuser or repair it.

What Does the Brother Printer Code E50 Mean? - Small ...
