Most scanners are supported by SANE. As that page states, the SANE project maintains a searchable list of supported (and some unsupported) devices. This list includes many but not all Epson scanners; some Epson scanners are listed as supported by the Epkowa driver but not directly by SANE. This page is an attempt to provide some help in getting such scanners up and running in Gentoo.
Epkowa is a proprietary driver for Epson scanners. It is not supported by a dedicated Gentoo package or by media-gfx/sane-backends but it is included in media-gfx/iscan which is a proprietary Epson scanner utility. Gentoo users may prefer to use a non-proprietary utility such as media-gfx/xsane but these packages rely on media-gfx/sane-backends which provides no support for the Epkowa driver, probably because Epson firmware is involved. The Epkowa driver can be used in the same way as other backends in media-gfx/sane-backends, for help on how to achieve in the absence if a dedicated package see the Guide (below).
