Steps To Fix HP Printer is Displaying A 50.4 Error Message

1. First thing you have to do is to cancel all the pending printing jobs in the queue.
2. Now switch-off your printer and leave it for few seconds to cool it down.
3. After cooling down the printer completely, the fuser failure error appears on the display screen.

On alot of printers when you print envelopes theres a back door on the printer to prevent the curling or wrinkles. Just open the back door when doing envelopes.

Best of luck and have a happy and safe 4th of July weekend!

HP recommended checks: 1. adequate 120 VAC power supply, 2. Remove Fuser Assembly, wait 5 minutes and then reseat. 3. Reset the printer to Factory Default settings (remember to copy down the IP address, mask and gateway numbers first).

While this may solve the problem, it is much more likely it's time to replace the fuser. Cost is approx $125 if you buy it online. Just do a Google search on HP 2840 fuser.

This link will show you where your fuser is and how to remove and replace it.

Hi ellenf971:
Here is your problem.
50.X FUSER ERROR
50.2 error - Fuser Failure (Abnormal Warmup).
Perform the following steps:
1. The connector between the fuser and the
printer is not connected properly. Reseat
the fuser. Check the connector J5013
between the fuser and the printer. Replace
it if damaged.
2. Break in the main thermistor. Turn the
printer off and remove the fuser. Measure
the resistance between the fuser
connectors J5013LA-2 (MAINTH) and
J5013LA-1 (GND). If it is not within the rage
of 330k ohms to 50k ohms (at ambient
temperature), replace the fuser.
3. Break in the fuser heater. Measure the
resistance between the fuser connectors
J5013L-2 (FSRH) and J5013L-1 (FSRN)
with the fuser removed. If it is not within the
rage of 12 ohms to 52 ohms (at ambient
temperature), replace the fuser film unit.
4. Faulty DC controller. PCB Replace the
DC controller PCB
you will have to get an HP certified technician to replace the fuser assembly.

Hope this helps

i have a machine just like that it is normal that the fuser gets hot is a laser machine, and the part with the envelope the tracks for the paper might be worn out you said that you use it a lot check that or clean the tracks

Envelopes can be printed from tray 1 or 2. Select the type of envelope you are using from the PRINT dialog box or the driver. In your program, set the margins. Typical margins for a commercial #10 or DL envelope would be: Return Address Top margin 15mm(0.6 Inch) Left margin 15mm(0.6 Inch), Delivery Address Top margin 51mm(2 Inches) Left margin 89mm(3.5 Inches). For the best print quality, position margins no closer than 15mm (0.6 Inch) from the edges of the envelope. Avoid printing on the seams of the envelope. Envelopes with a peel-off adhesive strip or more than one flap that folds over to seal must use adhesives that are compatible with the heat and pressure of the printer fuser. the extra flaps and seals can cause wrinkling, creasing and feed jams, could even damage the fuser.

From HP Website:

No, it's an ink jet printer

error 50 means your fuser assembly has gone bad or its not getting power to be functional. you need to replace the fuser unit.
