Looking for a sollution by error code was the first step.
I also tried to switch it off and on :-)
Now I'm in contact with xerox support centre.

Since i reinstalled a freenas server where is a folder for saving scanned documents, The Workcentre 7120 saves just epmty documents and empty folders with same name.
When i use the same username/password/path on any other device, it can read, write, delete files in the folder. But the workcentre reported an error 027-529. The freenas has two network cards and when i use an ip address of the another one, it works perfectly, but all other devices uses the first one and have no problem.
The workcentre and the freenas are in the same network, so no routers, firewalls, IP filtering, anything for security is used. Also in the log in freenas is visible opening session, creating a file, session timeout and R/W unlocking the new file, when the first IP adress is used.
I suppose the xerox remembered the NAS IP with some original signature and that is different after reinstall, and it confuses the xerox.
Is it possible to clear data about the NAS from the workcentre to let it obtain a new ones? Or if there is other reason why it's not working does anybody know, how to repair it?
