1) First thing is check power source. If you have the printer plugged into a UPS (uninterruptilbe power source) unplug it and plug it directly into the wall. If it is plugged into the wall you might want to try a different outlet to see if it solves the problem.
2) Remove and reinstall the fuser. It may not have seated properly.
#) Make sure you installed the correct fuser. Should be RM1-1082. There should be a sticker on the fuser with this number. See the following article for more info. http://www.partsnow.com/service_today/0705.asp

If you still have the old fuser check also that it is a RM1-1082. If not you may have a euro version machine which would require a different fuser.

If the fusers match up you should check the voltage coming to the fuser if possible. If there is 100- 127 volts where the fuser plugs in you probably got a bad fuser or it was damaged in transit. If there is low voltage or no voltage you may have a board problem. Probably DC controller or Power Supply.

How to reset fuser unit in printer hp laserjet 4250


turn the printer off for at least 20 minutes, then cycle power. If the 50.2 fuser error occurs again, you may need to replace the entire fuser assembly OR you will need to replace the power supply.

I have hp colour laserjet cm6040f mfp, that displays error 50.A fuser error. pls your help is so much important


You will need to order a fuser and replace it or call a service tech who can. The problem is that the electronics on the fuser have actually burned out, so that is why the whole fuser needs to be replaced.

Replace the fuser unit (they last about 75K pages in my experience)

1. Power down the printer and unplug it
2. Remove the fuser from the back side of the printer
3. Replace the fuser unit with a new one
4. Turn the printer back on

Dirty marks down centre of each page, has been cleaned but still getting marks, toner has been replaced also.


It seems you have a worn fuserunit. By replacing the fuserunit (RM1-1083) the problem should be solved.

50.4 FUSER ERROR ON HP LASERJET 4250n


I am willing to bet that you may have a faulty thermistor in your fuser asssembly, I wouldn't bother replacing the thermistor, your best bet is to just replace the fuser assembly and this should resolve your issue, so replace the fuser or call someone to do it for you. This should resolve your issue.

HP LASERJET 4250n PRINTER-PROBLEM WITH PAPER JAMS AND "FUSER ERROR"


Put a maintence kit in your machine, easy install, everything just clicks in, Every 200 000 prints it should be done, it includes the fuser, all feed rollers, sep pad and transfer roller.

These are great printing machine, they only ever need the MK and on this model a fuser drive gear wears and get noisy, but once that has been done once, it is ok from then on.
KIts seem expensive but they are meant to last 200 000 prints and usally do. These are one of the best most reliable printers in the market.
