I'm having Canon CR-Series scanner connectivity issues after updating to Windows 11 24H2

There's a Windows 11 24H2 device detection bug associated with CR-Series scanners which Canon and Silver Bullet Technology are aware of. 

After the update, symptoms might include: 

1. Scanner not appearing in device manager.
   
2. Not being able to scan with the Canon Scanning Utility or Ranger Flex. 
   

If your scanner stopped working after installing the Windows 11 24H2 update we recommend the following: 

1. CR-50/80/L1: upgrade the Ranger plugin to 2.1.1.62 or higher.
2. CR-135i/190i/190ii: upgrade the Ranger plugin to 2.1.2.21
   or higher.
3. If the above doesn't work, or your scanner isn't listed:
   Please attempt the following 
1. Download the latest Canon driver for the respective scanner.
2. Restart the WIA service.
1. Refer to the following article: "Windows 11 Scanner USB Connection Issue imageFORMULA Scanners"
2.  If the issue persists, try disabling the service.
   
3. Download and run Canon's registry fix tool.
1. It may be named something like "DR_RegistryFix.exe_download.xml" under "Software & Driver Results."
4. Restart the scanner and attempt to initialize and scan in Ranger Flex.

If none of these suggestions resolves the problem, please contact us.

Please note: with all Canon models, a proper reboot of both computer and scanner is recommended after installation.
