This fuser error can lead up to a series of solutions, and I will list them in order of easiest to hardest.

1) Unplug your printer from the wall, wait 5 minutes and plug it directly into the wall, UPS battery backups and Surge Protectors can trigger this type of error.

2) If you have another one of these printers, try swapping the fuser roller with another one while the power is off and see if the error persists upon startup.

3) Last and least desirable, you may have a failed Engine Controller Board, which is responsible for among many things, making sure the fuser is at the proper temperature and has no tears. Be aware that this repair requires a pretty serious disassembly, and can be daunting to a newcomer.

The fuser is actually considered a part replaced with routine maintenance, around every 100,000 to 150,000 pages. It is what is responsible for the carrying the charged toner particles and heating them up to melt them onto the target paper (New HP Laserjets use a wax based toner for better environmental impact) Problems with the fuser generally show themselves as lines or splitting images on printed paper, but if serious enough (as in a tear on the roller) can cause the printer to cease printing to prevent serious damage to the interior of the machine.

SOURCE: error 50 code, have replaced fuser and checked connections

I am not sure this will stay fixed but after i cleaned the pcb's and checked the connections and let the unit sit overnight the printer works just fine. If this does not stay fixed I will contact you again.
Thank you,

SOURCE: My hp 2420 printer show me an error 49.2FD9

power on your printer, after you see processing data the second time, press cancel.
Everytime I have seen this error is because the user tries to print a PDF file that is corrupt.
This has worked for me in the past.

Hp laser jet 2420 printer 50. error


This is an error with your fuser...you need another fuser...any 50.x error is related to that and they are something that needs replacing regularly(100-150k pages) the heat resister goes out or the film tears..ect....Try www.getthatpart.com for a good deal on a used one...Used are normally just as good as new for a lot less and these guys guarantee their units, they have someone you can call on the phone, so I recommend them. Hope this helps you.

Hp 4m shows service error 50


Hello,

The service 50 error indicates a bad fuser assembly. You can get one on Ebay for less than $50. To replace the fuser just open the door on the back of the printer, inside you will see the fuser, unscrew the 2 screws and pull the old one out. Insert the new fuser and screw it down, power on the printer and you should be good to go.

I hope this helps, If so please rate our solution.

Hp 2420 vrtical line in page


Hello,

This issue can be due to fuser. I am sure you have changed the toner cartridge.
To confirm its a fuser issue, please perform the following:
1. Try printing a configuration page from tray 1, pull the top cover, as soon as the media is 60-70% inside the printer.
This would stop the paper before reaching the fusing assy.
2. Remove the paper and check if the line exist.
If exists, fuser is not faulty.
If it does not, then transfer roller, laser/scanner assy is faulty

- If fuser is faulty, perform the cleaning page as following
1. go to configure device > print quality > create/process cleaning page
perform cleaning page 5-6 times, however, if the line is due to fuser, then fuser needs to be changed.

Let me know the next update.

- Nikhil

50 service flashing on display screen


If the display panel reads 50 FUSER ERROR, CYCLE POWER, turn the printer off for 15 minutes. This allows the capacitor that is responsible for signaling this error to discharge. If you don't wait 15 minutes you will continue to get this error even if you have replaced the fuser. If it continues to show the error, then you need to replace the fuser. It is easy to replace.
The fuser maintenance kit is about $119. on the web.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
