Can I use my Epson Stylus CX6600 as a fax machine? Yes. If you have a fax modem and a fax application in your computer, you can use EPSON Smart Panel to create a virtual “fax machine” on your computer screen to send photos or text. The fax application must be installed before installing your Epson Stylus CX6600 software. Take note that Windows has its own fax utility.
