Hi romrussia,
Thank you for using the Support Forum. Please take a look at the solution for scanning to an SMB folder. If this does not help please consider contacting your support centre for further assistance.
Xerox WorkCentre 3345 does not scan to a shared folder SMBv2.
Although in the document named "Xerox Multifunction Device Scan to SMB Support" (placed at https://www.xerox.com/download/security/white-paper/1b926-5505a2a57c43e/Xerox-Product-SMB-Supported-...) written that the MFD hase the ability to scan documents to a server using the Microsoft Server Message Block (SMB) v2 protocol.
When will this problem be finally solved?
