Thank you!
Very detailed instructions with step by step actions.
Swift and timely response.
For anyone experiencing a similar issue, our print server was upgraded from an older version of windows to 2012 R2 64bit.
Prior to establishing an FTP server so that users can scan to network, I decided to try updating the firmware on the MFP.
Immediantly after updating, the printer was able to scan to the network share.
Thank you.
