Hello,
50.9 Fuser error message HP LaserJet P4014 P4015 P4515
If you are seeing the message 50.9 Fuser Error on your HP LaserJet P4014, P4015, P4015 series printer, you have either a failing fuser or the wrong model fuser installed in your printer. (The fuser is the consumable part in your printer which heats up and bonds toner to the paper. Usually the fuser gets replaced several times over the life of these printers.)
HP makes 2 different model fusers that look very similar -- the P4014/P4015/P4515 series fuser, and the M600 series fuser. Because of the similarities in appearance, sometimes the wrong fuser gets installed in the wrong model printer and triggers a 50.9 error.
The easiest way to check which model fuser you have installed is to pull the fuser out of the printer and look at the fuser's barcode. It is easy to remove the fuser on these models; if you don't know how to remove your fuser see the removal instructions farther down this page.
Once you have the fuser removed from the printer, look at the barcode as shown below to determine which model fuser you have installed. For the P4014, P4015, P4515 series printers the fuser part# should read RM1-4554 as shown in the picture below.
Either way, whether you have a failing fuser or an incorrect fuser on your LaserJet P4014, P4015, or P4515, you can purchase a quality replacement fuser in the maintenance kit for the P4014, P4015, P4515 series.

Removal instructions: How to remove the fuser from the printer
Turn the printer off and unplug the power cord. The fuser might be hot if you have been using the printer. As a safety precaution wait 30 minutes for the fuser to cool before proceeding.
If a duplexer is installed, remove it from the back of the printer.
Next fold down the rear door.
Flex the plastic arm-hinge (circled in red below) on the left bottom of the door . This will release the tab which holds the plastic arm in place, and will free the door.
While grasping onto both sides of the fuser, push the blue levers upward and pull the fuser straight out.
After you order a replacement fuser and it arrives, you can install the fuser by inserting the fuser and aligning the left side first. Push the fuser firmly on the left side, then the right--listen for the sound of both blue levers clicking into place. If the fuser does not click into place you run the risk of wearing out both the fuser and the gears that drive the fuser prematurely. Re-install the plastic rear output bin and you are ready to print.

Replace fuser assembly is the fix
Normal consumable, the lamp electrics (lamp, thermistor) will have blown.

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
