Try FaxZero. With this handy site, you can send a fax right from your computer without the added trip or hassle of fighting with a squirrely fax machine.
FaxZero allows you to send faxes completely free from your computer. You can attach up to three documents, with a total fax limit of three pages, including the cover page. There will be an ad on the cover page.
To use FaxZero, enter in the sender information on the green side and the receiver information on the blue side. Attach the pages you need and enter information into the text box.
This information will appear on the cover page, or you can select one of your attached pages to be the cover page. When you've entered in all of the necessary information, click the gray button at the bottom of the green section.
If you need to send more than three pages, FaxZero also offers to send up to 25 pages for $1.99.
