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.
