This error might display if the fuser temperature becomes too hot. Follow these steps to turn off the printer and allow the fuser to cool before printing again. Press the Power button to turn off the printer. Disconnect the power cord from the rear of the printer.
50.2 error indicates that the printer is not heating up fast enough. This can be caused by a bad heating element in the fuser but can also be caused when the printer does not have adequate power due to overloaded circuits or being plugged into a power strip or surge bar that limits current flow.
Plug the printer directly into a wall socket. Turn the printer back on. Often times the reseating the fuser and rebooting the printer will allow the fuser to reset itself. If the 50.2 Fuser error message returns, it`s time to replace your fuser and possible the power supply.
The message `Fuser Error` or `Self-Diagnostic` means either the fuser has reached the maximum temperature allowed or there has been an error in detection of the correct temperature during specific times of the printing process.
Streaking, smudging, black lines, and double images are all symptoms of a bad fuser. When you notice these printing defects and experience problems, such as paper jams or wrinkles, this is a good sign to replace the fuser kit.
The 50.1 fuser error message refers to a low temperature reading on your fuser. If you see the error message “50.1 Fuser Error” on your HP Color LaserJet 2820 or 2840 series printer, you probably need to replace the fuser. Fusers are a consumable part and are sold as part of a maintenance kit.
When a 50.4F. 00 error is displayed on the control panel, it indicates that there is an issue with the fuser or the power outlet where the printer is connected. Turn the printer off, and then back on to clear the error. Ensure that the power outlet, to which the printer is connected, is in good working condition.
A fuser unit is a pair of heated rollers within the printer that fuses the toner onto the paper being printed on. Toner particles are pulled to the paper to create the desired text and images as the paper passes the imaging drum.
If you have NOT recently replaced the fuser or heavily jostled the printer around, then the 50.2F. 00 Fuser error indicates you have an actual fuser failure and the fuser needs replacing.
50.AF is a low fuser temperature error and usually caused by a defective fuser. Resetting the printer is unlikely to resolve this error.
Fuser Units

The coating wears off and causes the toner to not fuse properly. There are replacement rollers and sleeves on the market that you can replace and turn a non-functional fuser into a good working one. Rebuilding fuser assemblies is not a new thing.

The fuser unit is a vital component of laser printers. Most fusers last between 50,000 and 200,000 pages, depending on the design.
The fuser unit or fuser is a critical part of any laser printer. Using pressure and heat, it fuses the toner powder onto the page to create a print, and without it, the printer cannot operate.
Printing made easy with an HP Fuser Kit

It lets you print up to 150,000 pages of dynamic quality before you need to replace it.

Your printer monitors the life of your fuser. When the fuser reaches the end of its life, the printer displays 80 Fuser Exhausted. This message indicates it is time for you to replace the fuser. For best print quality, make sure you replace the fuser when the printer displays 80 Fuser Life Warning.
