Hi @Jay9118,

Welcome to HP Support Community.  

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

If your HP Envy 7640 is not detecting a new image when scanning in flatbed mode, there could be several reasons behind this issue. Here are some troubleshooting steps you can follow to resolve the problem.

• Check the scanner settings: Make sure the scanner is set to flatbed mode and not to any other mode like ADF (Automatic Document Feeder) or duplex scanning. Verify that you have selected the correct source for scanning.
• Restart the scanner and computer: Sometimes, a simple restart can resolve temporary glitches. Turn off the scanner, unplug it from the power source, wait for a few seconds, and then plug it back in. Also, restart your computer.
• Update drivers and software: Ensure you have the latest drivers and software installed for your HP Envy 7640 scanner. Visit the HP support website and download the latest drivers specific to your operating system.
• Check for conflicts with other software: Sometimes, other scanning or imaging software running in the background can interfere with the scanner's operation. Try disabling or closing any other applications and see if the problem persists.
• Inspect the scanner glass and sensors: Dust, smudges, or debris on the scanner glass or sensors can affect the scanning process. Clean the glass and sensors carefully with a lint-free cloth and some isopropyl alcohol.
• Test with different documents: The issue might be specific to certain documents or paper types. Try scanning different documents or images to see if the problem is consistent.
• Reset scanner settings: If the issue persists, you can try resetting the scanner to its default settings. Refer to the user manual or the HP website for instructions on how to perform a factory reset.

I hope this helps. 
 

Take care and have a good day.
