Hi @8720USfan ,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with your HP OfficeJet Pro 8720 printer's touchscreen lights up but does not respond to touch input, this may indicate a hardware or software issue with the printer's display panel. Here are some troubleshooting steps you can try:

1. Restart the Printer

1. Turn off the printer and unplug it from the power source.
2. Wait for at least 60 seconds.
3. Plug the printer back in and turn it on.
4. Check if the touchscreen responds to touch input.

2. Perform a Hard Reset

1. With the printer turned on, unplug it directly from the power source.
2. Disconnect any USB or network cables connected to the printer.
3. Wait for at least 2 minutes.
4. Reconnect the power cord directly to a wall outlet (avoid surge protectors).
5. Turn on the printer and test the touchscreen.

3. Clean the Touchscreen

• Use a soft, lint-free cloth slightly dampened with water.
• Gently wipe the screen to remove any dust, smudges, or debris.
• Avoid pressing too hard while cleaning.

4. Check for Firmware Updates

If the touchscreen is partially working, try the following:

1. On the printer, navigate to Settings > Printer Maintenance > Update the Printer.
2. If this option is not accessible, update the firmware via the HP Smart app on a connected computer.

5. Reset the Printer to Factory Defaults

If possible, perform a factory reset:

1. Navigate to Setup > Printer Maintenance > Restore > Restore Factory Defaults.
2. Confirm and allow the printer to restart.

6. Test with the HP Smart App

• Use the HP Smart app to control printer functions and verify if it's only the touchscreen that is non-responsive.
• Download the app from the Microsoft Store or your smartphone's app store.

7. Inspect for Physical Damage

• Check for any visible damage to the screen.
• If there are cracks or signs of impact, the screen might need replacement.

I hope this helps. 

Take care and have a good day.

I have tried all these but it wont even let me do a hard reset. If I plug it in the screen lights up but nothing is there. The printer has been working perfectly fine with no issues but suddenly stopped in the middle of a project.
