hp printers typically do not have an error message to cover every known condition, thus if the printer needs maintenance in an undefined area, it will invariably indicate a paper jam. The printer usually responds to the installation of a maintenance kit which will include transfer roller, pickup rollers, and fuser.

FALSE FUSER OVERTEMP INDICATION, POWER SUPPLY THAT DRIVES THE FUSING UNIT. MODEL 8150 DOES THE SAME THING. TRY TO GET A REFUND ON THE FUSER?

A 50 Service error is a fuser error. Turn the printer off for at least 10 minutes, then turn it back on. If the error is still there, you can try reseating the fuser, but be sure to let the fuser cool completely before touching it.
If you still have the 50 Service error after reseating the fuser, you might need a new fuser.
You can access the fuser by opening the rear door. It's located directly above the paper tray. There are two screws that hold it in place. Remove those two screws, and the fuser slides outs.
Hope this helps.

Unless someone else replies with the identical fault and remedy, my best suggestion is to get a copy of the service manual. There may be a fee but you will be sure of following the correct diagnostic procedure. It sounds like you are capable of this. Good luck.
