In response to Kelsey's email request to test the system, I sent two faxes to my new Sonic e-fax number.
I encountered the exact error noted in the subject line. My PDF came out with text out of place, overlapping, and fonts in wrong size and style, essentially unreadable.
I tried re-opening the "bad" file from my first test fax, and it looks better with Foxit and Nitro Pro, but the bottom quarter of the page is still distorted.
My second fax was a complete success.
