Hi @JB10011,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are getting "Error 05" on your HP LaserJet Pro MFP M29w which typically indicates a paper jam or a paper feed issue. Here are some steps to troubleshoot and resolve the issue:
 

Power Cycle the Printer:

• Turn off the printer and unplug it from the power source.
• Wait for about 60 seconds.
• Plug the printer back in and turn it on.

Check for Paper Jams: Paper Jam Error.

• Open all covers and trays to inspect for any jammed paper.
• Remove any paper found carefully to avoid tearing it.
• Make sure no small pieces of paper are left inside the printer.

Check Paper Tray and Feed Path:

• Ensure the paper tray is not overfilled and the paper is aligned correctly.
• Inspect the paper feed path for any obstructions or issues.

Clean the Paper Feed Rollers:

• Turn off and unplug the printer.
• Open the access door and locate the paper feed rollers.
• Use a lint-free cloth lightly moistened with distilled water to clean the rollers.
• Allow the rollers to dry completely before closing the door and plugging the printer back in.

Reset the Printer:

• Turn on the printer and navigate to the settings menu.
• Look for an option to reset the printer to its default settings (usually under "Setup" or "Tools").
• Perform the reset and see if the error clears.

Update Firmware: Update the firmware on an HP printer 

• Ensure the printer's firmware is up to date. Visit the HP support website to download and install any available updates for your printer model.
