Using MSFax from MSWord changes my default Printer

Reposting this because I wrote the "Subject" description incorrectly .

When I send a FAX with MSWord, it sets my default printer to FAX permanently.
I have to manually go into Control Panel and reset my default printer from
FAX back to my Epson printer. Here's what I do. After completing my fax I
select FILE, SEND TO, FAX RECIPIENT and in the drop down box where you select
"Which of the following is your fax program", I select FAX (default is my
printer). I complete the rest of the steps and send the FAX and the fax is
sent.
How do I keep MSWord from changing my default printer from Epson to Fax?
Thanks for the help.
