Scan to Network (SMB) doesnt work | C1765nfw

Hello,

I'm trying to set up my printer to scan to a shared folder on my Mac, but unfortunately it doesn't work.
I want the printer to store scans on /Users/Shared/Scans on my Mac which has the static IP address 10.0.0.27 using the user 'guest'.

Connecting to the shared folder using an SMB client and the guest user (without password) works fine, but my C1765nfw always gives out the following error:

031-529 Scan
Anmeldung fehlgeschlagen (= login failed)

What do I need to put into the fields Server Address, Share Name, Server Path?

Thanks in advance, Fabian.
