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 these troubleshooting steps first:

1. Verify all physical connections are secure. Ensure both the power and USB cables are properly connected.

2. Unplug the scanner's USB connection and plug it back in.

3. Try connecting the scanner to a different USB port on your computer.

4. Check if the issue persists with other USB ports on your computer.

5. Restart your computer and reconnect the scanner.

6. Check for any recent system or Windows updates that might affect USB connectivity.

If the issue persists, try updating the device driver using the following steps:

1. Connect the computer where PaperStream IP is installed and the scanner via USB cable and power on the scanner.
   

   • Run Device Manager.
     

   • Right click on your scanner name (ex. fi-8190) under [Imaging devices], and select [Update driver].
     
     

   • Select [Browse my computer for drivers].
     
     

   • Select [Let me pick from a list of available drivers on my computer] and click [Next].
     
     

   • 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.
     
     

   • When the window displays [Windows has successfully updated your drivers], click [Close] to close the window.
     
     

   • 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.

If you're using a new scanner or have recently moved your scanner to a new computer:

• Ensure you've downloaded the correct drivers from the manufacturer's official website

• Check for any BIOS or USB driver updates that might affect device recognition

• For check scanners or specialized devices, contact the manufacturer or your bank for specific driver requirements

• When connecting to a docking station, verify the scanner is properly connected to both the dock and your computer

• Inspect the USB cable and ports for any physical damage

If your scanner's scan function suddenly stops working:

• Reset the scanning application (like PaperStream Capture) to default settings

• Verify and reconfigure the file path where scans are saved

• Delete any incorrect configuration jobs

• Restart the scanning application

• Test scanning multiple times to ensure stability

If problems persist after trying all these steps, contact your IT support team or the scanner manufacturer's technical support for further assistance. They can help troubleshoot access issues, restore account permissions, or resolve other technical problems preventing you from scanning documents.
