It is not mirrored. Most Epson ADF units turn the sheet over before scanning the flip-side but this one doesn't. As a matter of fact, how the flip-side comes out depends on the binding edge of the original in combination with whether the sheet is turned over or not. As *most* documents are bound on the long edge, flip-sides end up up-side-down with the ES-H300. > allan > > On Thu, May 31, 2012 at 11:27 AM, Jeff Rush <jrush at taupro.com> wrote: >> I'm working in the sane-epson2 backend, trying to get it to fully >> support adf-duplex for scanning both sides of a page, for the Epson >> ES-H-300 scanner.

The epkowa backend has flipping logic as of 2.27.0. While the released version depends on a non-free plugin, the code includes support for sanei_magic_rotate (and sanei_magic_deskew). You can find the epkowa backend sources in the iscan source tarball available from: http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX The latest version is 2.28.1.
