Lexmark MX310 ? Scanning Mixed Sizes Issue Using Lexmark Printer Home

What you will see

When scanning multiple documents with different sizes using the Auto-document feeder (ADF), if the size of the first document is “Letter”, the rest of the documents will also be scanned as Letter even though the paper sizes are different. The same result can be observed even should you set the Scan Size option to Mixed, Auto-size, or Universal.

On the other hand, if you start the scan using paper sizes other than “Letter” (e.g., Legal or A4) the results are in correct sizes.
