My colleague showed me how he can scan a document from the WorkCenter 3325 printer to his Mac (running macOS Sierra 10.12.6)- this isn't a scan to an email address; the scanned document is sent to a specified loction on the destination machine and I'm trying to set this up on my machine but I'm unable to see the Scanning tab in System Preferences (pictured); we've tried sharing the printer with all users but this hasn't worked and neither of us are sure what needs to be installed. Can anybody please help?
