@manojpandeycms, Welcome to the HP Support Community. 

Thanks for reaching out about your query regarding the HP LaserJet Pro MFP 4104fdw Printer.

We're thrilled to have the opportunity to assist you and provide a solution. We hope our assistance has been helpful! 

The error code 50.04.00 on the HP LaserJet Pro MFP 4104fdw indicates an issue related to the fuser unit, which is responsible for the heating element of the printer that melds the toner onto the paper. Here are some steps to troubleshoot and resolve the issue:

1. Power Cycle the Printer:

   • Turn off the printer and unplug it from the power source.
   • Wait for about 30 seconds.
   • Plug the printer back in and turn it on. This process can reset temporary fuser errors.

2. Check the Fuser Unit:

   • Ensure that the fuser unit is properly seated. You can access the fuser by opening the printer’s rear door or cover. Ensure all connectors are tight.
   • If you recently replaced the fuser, ensure it is compatible with your model.

3. Inspect for Overheating:

   • Make sure the printer is not in a location with excessive heat or inadequate ventilation.
   • Ensure there are no objects blocking any ventilation grills.

4. Environment Check:

   • Move the printer to a less humid or cooler environment to avoid any temperature-related fuser issues.

5. Service or Replace the Unit:

   • If the error persists after checking the hardware connections and environment, the fuser might be defective.
   • Contact HP Support for further assistance, as the unit might require professional service or replacement.

I hope this helps!

Take care and have an amazing day!
