Turn the printer off, wait 10 minutes, and then turn the printer on. 2. If the message persists, reseat the fuser. If that does not work, replace the fuser.
Set the output bin cover aside. While grasping onto both sides of the fuser, push the blue levers upward and pull the fuser straight out. Once you have correct fuser matched up with your model, install the replacement fuser by inserting it and aligning the left side first.

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.
