ADF works for copying but not scanning. Cleaned the rollers. Entered HP Envy 7649 serial # for support - says S/N not found.

Hi @Glockman414,

Welcome to HP Support Community.

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

It sounds like you've already taken some good troubleshooting steps by cleaning the rollers and trying to seek support from HP. Since the ADF (Automatic Document Feeder) works for copying but not for scanning, it's possible that there might be an issue with the scanning software or settings rather than a hardware problem.

Here are a few additional steps you can try.

• Check scanning software settings: Make sure the scanning software you're using is configured to recognize and use the ADF. Sometimes, scanning software defaults to using the flatbed scanner, so you may need to change the settings to use the ADF.
• Update drivers: Ensure that you have the latest drivers installed for your HP Envy 7640. Sometimes, outdated drivers can cause compatibility issues. You can download the latest drivers from the HP support website.
• Reinstall scanning software: Try reinstalling the scanning software or using a different scanning application to see if the issue persists.
• Reset printer settings: You can try resetting the printer settings to their default values. This can sometimes resolve software-related issues.
• Check for firmware updates: Ensure that your printer has the latest firmware installed. Firmware updates can sometimes address compatibility issues and improve performance.

If you're still experiencing issues after trying these steps, it's possible that there may be a hardware problem with the ADF mechanism itself.

I hope this helps.

Take care and have a good day.
