@stanber, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Device Not Connected Error When Scanning! 

We're thrilled to have the opportunity to assist you and provide a solution.  

If you are experiencing an error where your scanner shows "device not connected" even though it was previously working, follow these steps to resolve the issue:

Check the Connections:

• Ensure that all cables connecting the scanner to the computer are secure and properly plugged in.
• Disconnect and reconnect the USB cable or any other connection types used.

Restart the Devices:

• Turn off the scanner and the computer.
• After a few minutes, turn the scanner back on first, then the computer.

Update or Re-install Drivers:

• Check the manufacturer's website for updated drivers for your scanner model.
• If an updated driver is available, download and install it.
• Alternatively, you can uninstall the existing scanner drivers and then reinstall them.

Check Device Manager:

• Open Device Manager on your computer.
• Look for any warning symbols next to the scanner device.
• Right-click the scanner device and choose "Update Driver."
• If the device is not listed, try connecting to another USB port or another computer.

Verify Software:

• Ensure that the scanning software (e.g., HP Utility) is correctly installed and not corrupted.
• Reinstall the scanning software if necessary.

Check Scanner Settings:

• Make sure the scanner settings in the software are correctly set to the connected scanner.
• Verify that the correct scanner is selected if multiple devices are connected.

Run Troubleshooter:

• Use the Windows troubleshooter tool for devices and hardware.
• Go to Control Panel > Troubleshooting > View all > Hardware and Devices, and then follow the instructions.  

Hope this helps! 

Take care, and have an amazing day!
