It would appear that there is an inherant problem with the machines firmware.
I have spent many many hours on the phone to tech support, each time going round in circles seting up new SMB shares in the address book, only for it not to work again.
This machine will not scan to Linux shares despite every other device saving to the share without a problem, including the scanner that the xerox has replaced.
This machine will also not scan to a windows share unless there is a password setup on the windows machine, the anonymous checkbox option is useless. Oh and it demands you enter a domain, which you might not have.
If you want to scan to a network location, and you probably do, dont buy this machine.
