The 52 Scanner error indicates that the printer has experienced an internal hardware error. Turn the product power off, wait at least 30 seconds, and then turn the product power on and wait for it to initialize. If you are using a surge protector, remove it. Plug the product directly into the wall socket.
A 52 error code is related to a failure of the laser scanner, the device writes the image to the drum unit in the printer before the toner is transferred to the drum. If powering off and leaving off for a few minutes does not clear the error then most likely the scanner is dead.
Replace the dc controller. In most Laserjets, a 52 error means the scanner motor is rotating at the wrong speed or not at all. In the case of the 5000 and 5100, it can also mean the scanner shutter failed to open because a lever in the printer was not actuated due to a missing toner cartridge fin.
Check the cabling carefully, you may have damaged the Flat flexible cable that plugs into the scanner or pinched the wires that run across the front of the scanner. Also the codes are usually 52.
The error displays for scanner hardware or power issues, such as a scanner bar jam or calibration issue, low scanner bulb temperature, or an internal or external electrical problem.
On the device control panel, press Menu/Enter. Use the < or the > button to select Service, and then press Menu/Enter. Use the < or the > button to select Restore defaults, and then press Menu/Enter. The device automatically restarts.

Error 53 indicates that the tape is at the end of its roll.

Recommended action. Turn the printer off, wait 15 seconds and turn the printer back on (using the power switch located on the back of the printer). The error code should not appear again.

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.
