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 folder and 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.
Has anyone ran into any issues with network scanning when the target is an EMC Isilon NAS. We have a large number of Xerox printers and so far have only been able to get the 5150's to scan to the Isilon. We currently have a ticket open with EMC support but was wondering if anyone else has had issues. We previously scanned to an EMC Celerra and did not have any issues. The specific model we are troubleshooting now is a Workcentre 5335. We get a 027-529 error which we can't find a description for and the only hit on it on Xerox support site is anothe user that had isues with the Isilon but there was no resolution in teh discussion. I am our storage admin so have limited knowledge of these printers but have been told it has the latest version of firmware. any help or guidance would be greatly appreciated. Calls to Xerox support have not gotten anywhere other than they are not aware of any issues with isilon. Thanks in advance
