This is normal. The problem is with Microsoft Photo Editor. Photo Editor expects the horizontal and vertical resolutions to be the same. This is not the case with faxes. A standard mode fax has near twice the horzontal res compared to the vertical res.

If you send the fax in fine mode you double the vertical resolution, and it will look better in Photo Editor.

Most image viewers on Windows do the same thing as Photo Editor and show a received fax the same way. I currently use alternatiff to view faxes on windows machines. It displays the faxes correctly, not half vertical size. It is a browser plugin and is available at and yes it's free.
