yz Fuser error To continue turn off then on is displayed on the control panel, it indicates that there is an issue with the fuser. The XX and YZ are two digit codes that provide information on the specific issue causing the error. Press the power button to turn the printer off, and then back on to clear the error.
00 Fuser error indicates you have an actual fuser failure and the fuser needs replacing. Fusers are a consumable part and they are the main component in a printer maintenance kit; it is expected over the life of the printer you will replace the maintenance kit several times.
(From: Tom Dunn ([email protected]).) Error code 51 indicates loss of laser beam for over 2 seconds. Check -5 V, also make sure there is no interlock mechanism damage, and +5 V at J451-1 on Laser Drive PCA. You may need new laser unit.
I found the following: Error 50 means that the heating of the fuser unit is no longer working. This is usually a burnt-out heating lamp,or a defective thermal fuse.
Error 50 is Invalid destination number.
50 error is a fuser error and means the fuser needs to be replaced. Do a search for the part on google and then see if it is worth repairing based on cost of the fuser and if you will need to hire someone to replace it for you.
If you are experiencing a “50.7” 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.
If you see this error code 50.5 on an HP LaserJet 4200, 4240, 4250, 4300, or 4350 series printer, the fuser installed in the printer is registering as an incorrect fuser for that model printer.
The laser scanner assembly is a fairly common part to fail on the HP LaserJet P4014, P4015, and P4515 models. If you are seeing repeated error codes of 51.10 or similar, you should replace the laser scanner.
Most printers will stop working when they`re out of paper, ink or toner, or if the unit detects an issue with the ink or toner cartridge. When this occurs, you might receive an error message or notice blinking green or amber lights on your printer.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
Er/30 or Er/50 to Er/55 displays and the Attention light is on. The printer is in an error state. Reset the printer to resolve the issue. With the printer turned on, disconnect the power cord from the printer.

Error code 50 usually refers to the fuser or part of the print assembly: https://www.printertechs.com/printer-troubleshooting/hp-error-codes/195-numeric-error-codes-50-59-hp… Try to look up the event log on the printers control panel or EWS.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
