Hi ryan.meyers,
Thank you for using the Xerox forum.
I would suggest that you review the Xerox 5335 Support site solutions and see if they can help identify your issue.
I searched on that site for scan to network folderand there were a few different solutions that may help as you can see in the following screen cap.
You may consider contacting the support center and request 2nd level customer support by calling 1-800-821-2797. They can further troubleshoot and recommend next steps to a resolution.
