I did an Internet search and tried out VueScan by visiting this web site:  https://www.hamrick.com/

They allow you to try the VueScan software out before you pay them any money.  My tests worked so well that I purchased the software.  It is so simple to scan any document.  And, by the way, the CanoScan 8400F is a very impressive scanner.
