Hi @Havenhome ,

Welcome to The HP Support Community.  

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

I understand you're experiencing difficulties scanning from both your computer and your HP printer, despite not receiving any error messages. 

Here are some troubleshooting steps you can try:

• Check connections: Ensure that your printer is properly connected to your computer via USB cable or network connection, and that it is powered on.
• Restart devices: Sometimes, a simple restart can resolve connectivity issues. Restart both your computer and your printer, then try scanning again.
• Update drivers: Make sure you have the latest drivers installed for your HP printer. You can download them from the HP website or use the HP Smart app to check for updates.
• Verify scanning software settings: Check the settings of your scanning software (such as HP Smart) to ensure that the correct scanner is selected and that it's set up properly.
• Run Windows troubleshooter: Windows has built-in troubleshooters that can help identify and fix common issues. You can access them by typing "Troubleshoot" in the Windows search bar and selecting the relevant troubleshooter for scanning or printing.
• Check for conflicts: Sometimes, other software or drivers can interfere with scanning functionality. Try disabling or uninstalling any recently installed software or drivers to see if that resolves the issue.
• Reset printer settings: You can try resetting your printer to its default settings. This process varies depending on the printer model, so refer to the printer's manual for instructions.
• Test with another device: If possible, try scanning from another computer or device to see if the issue persists. This can help determine whether the problem lies with the printer or your computer.
