If you are seeing a “50.1 Fuser Error” on your HP LaserJet 5000 or 5100 series printer, you probably need to replace the fuser. Fusers are a consumable part and are sold as part of a maintenance kit; it is expected over the life of the printer you will replace the fuser several times.
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.
The P4014 series use a thin fuser sleeve as a medium to heat the paper. Error 50.8 suggests one end of the fuser is not heating up which may be damage to the sleeve or heavy media.
50.1 error message indicates a fuser under-temperature error. The fuser did not reach the correct operating temperature during the warm up process causing a 50.1 error. This could indicate a problem with the power source or it could be paper stuck in the fuser if the 50.1 error follows a paper jam.
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.
Error 50 is Invalid destination number.
The 51.01 and 51.1 errors are fairly common error codes on the HP LaserJet 4100, 4100N, 4100TN, and 4100DTN series printers. This error indicates a failure with the laser scanner assembly, which is a high-failure part on these models.
Issue Description: 50.7F00 is displayed on the control panel and printer may also experience frequent or constant paper jams in the fuser. Remove the fuser. On the right side of the fuser near where the fuser engages the fuser drive assembly, check if the alienation flag is broken (see the two examples below).
If you have NOT recently replaced the fuser or heavily jostled the printer around, then the 50.7 Fuser error indicates you have an actual fuser failure (the gearing pressure is not releasing) and the fuser needs replacing.
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.
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.
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.

Error Code 51.1 says Printer Error No Kidding.lol
ANSWER : Sometimes turning off and on will allow you to print a few pages. The error is a beam detect error. The only real fix is to replace the laser scanner unit. Could be a loose connector on the scanner or DC controller from the scanner. That’s unlikely. You could try the only other free fix which is to open the scanner assy. and clean all the mirrors inside. The dust could obstruct the laser beam enough to cause the detect error.

Error Code 52.1M
ANSWER : Magenta laser error. The spinning motor bearings cause the squeal and that slows it down causing the error. You could try opening it and lubricating the motor shift with a drop of synthetic lubricant. Do not use more than a drop.
