Although my scanner is recognized by Windows, a scanner-not-found error occurs

Even though the device is detected in the Windows Settings app under "Printers & scanners" of "Bluetooth & devices", if you are unable to scan, please try updating the device driver using the following steps.

1. 1. Connect the computer where PaperStream IP is installed and the scanner via USB cable and power on the scanner.
      
      
   2. Run Device Manager.
      
      
      
   3. Right click on your scanner name (ex. fi-8190) under [Imaging devices], and select [Update driver].
      
      
      
   4. Select [Browse my computer for drivers].
      
      
      
   5. Select [Let me pick from a list of available drivers on my computer] and click [Next].
      
      
      
   6. Click your scanner name (ex. fi-8190) on the [Select the device driver you want to install for this hardware] window and click [Next]. If the scanner name is duplicated, select either one.
      
      
      
   7. When the window displays [Windows has successfully updated your drivers], click [Close] to close the window. 
      
      
      
   8. Scan a document to confirm the issue is solved.

Note: The issue will occur again when the scanner is connected to another USB port. In that case, please follow the steps above again.
