(after firmware update)
to scan into NFSROOT (CIFS enabled and anonymous access):
method 1:
on printer: "[i]" => "Local Drive" => "Open Folder Feature" => "nfsroot" => "<i>" => "<i>"
method 2:
on address book add this smb server: ip 127.0.0.1 / port: 445 / domain: workgroup / folder: "FOLDER_NAME"
(create FOLDER_NAME on network folder: \\PRINTER_IP\NFSROOT\ )
on printer: scan to smb
-----
many times scan to network doesn't work, it is a good alternative solution, scan to nfsroot and copy the file from this network folder
