How can I recover my original scanning program for Epson Artisan 810 printer?
There is a very easy way to acquire the scanning utility for your Epson Artisan. The support website provides users the possibility to download all there was released for this printer. I have checked and you can download the drivers, utilities, manuals, etc. It's basically what you would have on a support CD.
Access the page through the following link and then you can download the necessary packages: http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?UseCookie=yes&oid=132634&infoType=Downloads
