We have an HP 3550 color printer that has a 50.1 Fuser Error. Will replacement of the fuser correct the problem?

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!

Try using the HP Print Diagnostic Utility in Windows - HP Customer Care (United States - English)

Have the fuser replaced.

You need to ask them to change the fuser..The fuser is the part of the printer that actually melts the toner onto the page. Here is a website that gives you more info on the fuser so they can't B.S. you anymore..either the fuser works or it doesn't..

Please rate this solution thanks.

I can tell you that it is NOT the Fuser unit. I would change the drum unit first. This would be the most likely cause.

Bad or the wrong fuser installed.

Hello,
The fuser error 50 means that the fuser heater lamp is blown and you need to get another one (whole assembly). I personally use printerworks at www.printerworks.com to order a new one if you want to do it yourself, otherwise you will need to drop it off at an HP Authorized repair center..

Good Luck!

50.1 error is usually a fuser low temperature error. The thermistor (electronic termometer) that controls high and low temperature is either obstructed, damaged or the heating element inside the fuser has been brokem or damaged. Carefully remove and inspect the fuser. If you have no obstructions then the fuser will have to be replaced.
