Hello, @JanJaw.

Thank you for reaching out to the Community. I'd be glad to provide you with some information about the Scan Manager.

Let's go ahead and do some troubleshooting steps and get this squared away. Since you're having issues scanning your documents, there may be some issues with the scanner or settings that need to be configured. Be sure to check and do the following:

• Make sure you're using a TWAIN-compliant scanner.
• Test your scanner outside of QuickBooks to make sure it's working correctly.
• If the scanner isn't working outside of QuickBooks, contact the scanner manufacturer or an IT expert to resolve this.
