Win10 Fax and Scan sends a totally black page

I built a new computer last week and naturally upgraded from Win7 and put Win10 on the new build. My wife's a teacher and sometimes needs to Fax lesson plans when she needs a substitute to take the class. When I scan and fax a page everything seems to go fine and the other end gets the Fax OK. The problem is that it's a blank, totally black, page. Again I'm using the Win10 Fax and Scan software. I bought a new internal USR PCIe Faxmodem 5638. USR comfirms it is win10 complaint. The drivers are up to date and the test modem function in Devise Manager says it's working fine and is setup on Com3.

Any thoughts on what's going on?

How is content getting to the fax program? Print to Fax?

No, It is getting to the fax program by scanning using the Win10 Fax and Scan features. The visual preview from within the S&F program shows a normal scan and looks great.

As a test, suggest you create something in a program like notepad, etc. and print to Fax.

OK, I'll try that. I'll have to wait till Monday when the school is open. I don't know anyone who has a fax machine.

Well I gave up on MS Fax and Scan. I downloaded Essential Fax and got it working. I had to change the initialization string and re-install the driver to get it to work. I made the same change to MS Fax and Scan but it still wouldn't work.
