Hi @David Ritchie ,
What is MFC? The scanner brand?
If yes, in my opinion this problem is more related to scanner settings, you can try to post this issue to the scanner brand's forum. The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
If my understanding is incorrect, please be a bit more precise to provide more information so that I can get more accurate solutions to this problem. I’m glad to help and follow up your reply.
