Lexmark x5650 Scanning Issue

I just received a Lexmark x5650 All-In-One (AIO) printer.

Using ExactScan, I noticed that even though I indicated to use the ADF, ExactScan would stop after the first page in the ADF, instead of scanning all the pages in the ADF into one PDF.

I cannot find how to change this behavior so that all documents in the ADF will be scanned before the final PDF is OCR’ed and saved to DevonThink.

Has anyone run into this problem and solved it? Any guidance appreciated.

Thank you,
