I just purchased the Epson XP-7100 when I try to use XSane or Simple Scan I get the warning on all my three ubuntu boxes scanner not found. I downloaded and installed the software from the Epson site
I am running Ubuntu 18.04LTS on one, UbuntuStudio 18.04LTS on another and the 3rd Xubuntu 18.04LTS The last time I used Epson it worked with out a problem. That is the reason I dumped the iffy Canon. Where do I start looking?
