On most hp color printers this error tells you the yellow laser/scanner has an issue. Most times you will need to take it in for service.
Any of these error codes (51.20 51.21 51.22 51.23) points to a failure with one of the laser scanner assemblies on the HP Color LaserJet 4610 an 4650 series. To solve these error codes, replace the corresponding laser scanner.
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.
During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.
The laser/scanner assembly needs to be replaced as one of the motors has gone bad inside the assembly.
That error code indicates a failure of the yellow laser scanner. Unplug and leave for a few minutes, also make sure you are plugged directly into the wall and not into a surge protector.
This error code occurs when the Dpcdll.dll file is missing or corrupted.
When a 50.22. 00 or a 50.22. 11 error displays on the control panel, it indicates an issue with the fuser warming up. Step 1: Turn the printer off, and then on.
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.

A Scanner Error 22 error message displays on the printer control panel when you try to scan from the printer. This error might display when extra weight or pressure is applied to the scanner glass, such as when scanning an open book. The weight or pressure can stall the scanner mechanism.
The 41.2 error in the LaserJet 5Si, 8000, 8100 and 8150 is typically caused by high voltage arcing that disrupts the beam detect circuit. The most common cause of arcing is a bad connection to the transfer roller.
If the error is a 51.23 and your printer is an hp color laser printer, then you have an issue with the yellow laser/scanner not working. It could be the dc controller or the laser/scanner, however due to the cost of repair it will probably be best to replace the printer.

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.
