So that the Community can help you better, we need to know exactly which operating system is running on your computer (i.e. Windows or macOS, and which version thereof), how your printer communicates with your computer (i.e. via USB or Wi-Fi), and which app you're using to scan. That, and any other details you'd like to give will help the Community better understand your issue!
If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.
Thanks and have a great day!
