How to resolve this error???????
You will need to replace the fuser.

error 50 means your fuser assembly has gone bad or its not getting power to be functional. you need to replace the fuser unit.

From HP Website:
50.X FUSER ERROR
Description
A fuser error has occurred.
Action
SOURCE: Fuser Error 50.1 Fuser is hot. What is a fuser?
MAKE SURE THE PRINTER IS OFF AND INPLUGED BEFORE YOU START! The fuser is located in the back of the printer. You should see two blue pads where your index finger and thumb (on both hands) should pinch together then pull the fuser out. Re-seat the fuser back into its original position and wait 20 minutes before turnging Unit back on. If you do not wait 20 mins then the 50 error will appear again even if the problem is fix. Once you wait 20 minutes and it still gives you a 50 error you must replace the fuser. I have a great place to purchase fuser so let me know if you nee contact info!
SOURCE: 50.1 fuser error on HP 8150 LaserJet Printer
I have a HP LaserJet 5000 with a Fuser Error code 50.1, meaning low temp. I am not a tech, but I have been repairing my own cars, printing presses, computers, printers and anything else that breaks for over 35 years. The previous fuser on my LaserJet 5000 lasted over 7 years and while I was not getting any error codes, it was not fusing laser plates as well as I liked. Until recently I had two HP 5000 LaserJets and was able to trouble shoot by swapping parts. I replace a bad DC controller board in this particular printer about a year ago. Shortly after that I replaced the fuser with a genuine OEM HP fuser and it fused great for nearly a year. A few weeks ago I had a massive paper jam in the fuser and a day later got a Fuser Error 50.1. After checking the Internet I determined it might have broken the ceramic heating element. I swapped fuser with the one in my other identical working printer and the fuser error went away. I swapped the fusers back again and the error returned, pretty much proving the problem is in the fuser. Since I am not made of money I figured I could rebuild a fuser just as well as anyone else so I went on a search for the parts, but it was like calling Area 51 and asking what they were hiding. The service manual indicated some ohms testing to be done on the problem fuser and all results came back showing all the correct readings. I knew the fuser was the cause of the error, and the parts were not cheap so I carefully disassembled the fuser to see if I could isolate the exact part that was broken. The ceramic heating element and everything else looks fine. One detail I had found odd was that the printer used to take a couple of minutes or more to heat up, but I now got the fuser error 50.1 within 15 or 20 seconds of powering it on. This made me wonder if it would even have enough time to heat up enough to know it had a low temp problem. I thought the problem might be in the part that actually measured the temp. While I had the fuser apart I found one small resistor attached to the frame directly under the main drive gear. I did an ohms test on the resistor and it showed bad. I really hate to tear my good fuser apart to swap the resistors for fear I might burn it up to, so has anyone out there heard of a bad resistor causing a 50.1 error? I found only one reference on one site about a different LaserJet with a 50.1 code because of a bad resistor, and I have no idea where that resistor is on that particular printer. I know I could have just replaced the fuser by now, but I like to learn how things work and solve puzzles like this one. I am hoping some of my info may be of help to someone and if anyone has anyone ideas or thoughts on my comments, I would love to hear them. I will go on a search for a resistor next week and see if that helps. I hope to hear from someone soon. Thanks and God bless. James
