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.
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.

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.

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.
