Scanning XEROX ColorQube 8900S SMB / FTP

Hello,

I have some problems with Scanning to a folder with our CQ 8900s.

At first I told the CQ 8900s to  Scan all documents over SMB to our Win 7 (64Bit) PC.
That works fine. But after 2-3 Days i get a problem.
The printer told me they have no access to the Scanning folder. Access denied.
All other services and connections working fine. Also the access with the User I createt for the SMB connection.

To fix this problem I have to restart both systems in a correct order.
First restart the Win 7 PC and then restart thet CQ8900s.
I don't know why but this is they only way.


So i decied to give a  **bleep** of SMB and changed to FTP upload.

I installed FileZilla Server.
this works great since 2 month withou restarting any system. BUT !!!

**bleep** is that **bleep**.
The FTP upload alway creates 3 Folders.

On of the folder called "Scan010.LCK" with an LOCKINFO.DAT inside, wich told me 9c:xx:xx:xx:xx:0d CREATE

The other on has the same name as the PDF file as it is created. (If the pdf file is: "mycompany-2015-10-01@11-38-37.pdf" so the folder is named "mycompany-2015-10-01@11-38-37") -> and inside this is an other LOCKINFO.DAT, wich told me 9c:xx:xx:xx:xx:0d CREATE

And last but not least it creates an folder like this "xcse6889" with nothing inside.

I have no idea why this happend. I found no setting to change this.
And so i have to clean every houre our scaning folder from this mess.

Maybe someone can help.

Excuse my insufficient English skills, please.
