Hi @precious2501,

Welcome to The HP Support Community.  

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

I understand you are getting the red light on your HP DeskJet 2721e All-in-One Printer, which typically indicates an error that needs to be resolved. 

Here are some steps you can follow to troubleshoot and fix the issue:

Check for Error Messages:

• Look at the printer's display (if it has one) or on your computer screen for any error messages that might give more details about the problem.

Check Ink Cartridges:

• Make sure the ink cartridges are installed correctly.
• Remove and reinstall the cartridges to ensure they are seated properly.
• Check if the ink cartridges are empty or damaged. Replace them if necessary.

Check for Paper Jams:

• Open the printer and check for any paper jams or obstructions.
• Remove any jammed paper carefully to avoid damaging the printer.

Check the Paper Tray:

• Ensure the paper is loaded correctly in the input tray.
• Make sure the paper guides are adjusted properly to hold the paper securely.

Reset the Printer:

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

Update Printer Firmware:  Update the firmware on an HP printer

• Make sure your printer firmware is up to date. You can check for firmware updates through the HP Smart app or the HP support website.

Use the HP Smart App:

• Open the HP Smart app on your computer or mobile device and check for any maintenance or diagnostic tools that might help identify and resolve the issue.

Perform a Printer Diagnostic:

• Use the HP Print and Scan Doctor tool (available on the HP support website) to diagnose and fix any issues with your printer.
