- Reconnect the Scanner: Unplug the scanner from your computer and then plug it back in. Ensure that it is powered on.
- Check Device Manager: Go to Device Manager on your computer and see if the scanner is listed under "Imaging devices". If it has a yellow exclamation mark, there may be a driver issue.
- Restart Windows Image Acquisition (WIA) Service: Sometimes, the WIA service may not function properly. You can try stopping and restarting this service:
- Press
Win + R, typeservices.msc, and hit Enter. - Find "Windows Image Acquisition (WIA)" in the list, right-click it, and select "Restart".

- Reinstall Scanner Drivers: If the scanner is still not recognized, consider uninstalling the scanner from Device Manager and then reinstalling it. You can also check the manufacturer's website for the latest drivers.
- Try a Different USB Port: If you are using a USB scanner, try connecting it to a different USB port on your computer.
- Check for Windows Updates: Ensure that your Windows operating system is up to date, as updates can sometimes fix compatibility issues.
