So that the Community can help you better, please let us know whether you want to learn how to scan or if you already know how to scan and you just need help finding your documents. It would also help us to know exactly which operating system is running on your computer (i.e. Windows or macOS, and which version thereof) and which apps you're trying to scan with. That, and any other details you'd like to give will help the Community better understand your issue!
