Re: Fuser 50.1 Error

HI Ann, The problem you are having is the Fuser assy that heats and bonds the toner to the paper needs to be replaced. Once replaced this will fix the problem.Good luck!!!

Hp laserjet 3055 has error message on copying "50 fuser error, turn off then on". Restarting brings on the same message when copying.

The all-in-one has experienced an internal hardware error.

1. Turn off the power by using the power switch, and then wait at least 30 seconds.
2. If a surge protector is being used, remove it. Plug the all-in-one directly into the wall socket.
3. Check the cabling connections to the heating element.
4. Turn on the power and wait for the all-inone to initialize.
5. If, the error persists, replace the fuser.
NOTE The device power mustremain off for at least 20 minutes forthe fuser to cool down and correctly reset.
Turn off the power switch, wait at least 20 minutes, and then use the power switch to turn on the all-in-one and wait for it to initialize.

Regularly getting error code 50.9 on a HP color laserjet 3550 printer

Hey Joe,
This is what the HP Website has to say about it:
50.X FUSER ERROR Description A fuser error has occurred. Action
  1. Turn the printer off.
  2. Verify the fuser is properly installed and fully seated.
  3. Turn on the printer.
  4. If the message persists, contact HP Support.
BUT! you can try performing a cold reset, and maybe this would help:
500, 3550, 3700, 4600, 4650, 5500, 5550, 8500, 8550, 9500) use the instructions below. 1. Turn the printer on.
2. When the memory starts counting on the control panel, press and hold the green SELECT button. Continue to hold green SELECT button until all three Control Panel LED's are illuminated and on solid.
3. Release the green SELECT button.
4. The control panel will display SELECT LANGUAGE.
5. Press the DOWN ARROW button until control panel displays COLD RESET.
6. Press green SELECT button. The printer will perform a cold reset and then continue its power-on sequence.

Good luck!

HP Color LaserJet 2840 keeps showing 50.2 Fuser error message. Nothing helps correct problem. What to do? Have tried repeatedly turning printer off, waiting several seconds and turning on again. Each time...

The fuser is the heating unit near the paper exit, and that error means the lamp is burned out, the overtemp sensor is out, or the thermistor in the fuser is bad. About all you can do is replace the fuser. will have a new fuser for you.

. 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. To check the fuser, turn the printer off and remove the fuser. Measure the resistance between the fuser connectors. If it is not within the proper range, replace the fuser. If there is not continuity between the fuser connectors neutral and hot with the fuser removed, replace the fuser. If the problem is not related to the fuser, replace the engine controller board.

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.
