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.
If you are experiencing an “50.2F. 00 Fuser error”, first turn the printer off and back on. Sometimes the error will temporarily go away with a reboot so you can print a few more pages, but usually the error reappears.
Dampen a cloth with water and wipe down the outside of the printer. Don`t use cleaning solutions, especially ammonia-based cleaners, because the fumes may damage the printer`s internal components.
The Fuser is the piece that fixes the toner on the paper. This, like any other consumable part, wears out with the regular use of prints, since it is one of the components that suffers the most due to its mechanical wear and overheating of its components, due to the high temperatures it must withstand.
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.
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 LaserJet 6P and 6MP were introduced October 1996. They included infrared technology, for wireless printing.
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.

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.
The message “Fuser Kit Low” or “Fuser Kit Very Low” on your HP Color LaserJet M553 series printer is a warning that you have reached the recommended number of prints for your fuser assembly. (The fuser assembly is the consumable part in your printer which heats up and bonds toner to the paper.
An Er/04, Er/05, or Er/06 error message indicates a paper jam. Find and clear the printer of any jammed paper, or reset the printer if the printer has no jammed paper.
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.
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.
The fuser melts the toner particles, binding them to the page. The speed at which the paper passes through the fuser is what keeps the paper itself from burning. If the speed were slower, the paper would combust and burn.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking
ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.
