I have reviewed your comments and can't get it to work. For clarity, I am not trying to scan to a computer; I am trying to scan to email. Again, I am scanning from the MF743 directly. I hit scan to email, choose the email from the list, hit apply, start the scan and everything seems fine. It say scanning on the display, it finishes with no issue but then immediately prints a " TX Result Report." that just says "Error" followed by my email address which is a correct email. I have tried several different emails addresses to make sure. I get the error report every time. Also, I will add that I can scan to an USB stick just fine. Just cannot get it to scan to email.
