I have not had any need to set up a fax and can not advise personally....but browsing the help file also gave a few websites that may be useful.
This was one
http://windows.microsoft.com/en-us/windows7/Set-up-your-computer-to-send-and-receive-faxes
I use the included Windows 7 fax utility. The first time I used the utility, I sent a document that I called "test fax". Ever since, all documents that I send, regardless of their name, are listed in the column of the fax utility under "document name" as "test fax". What is that?
