You don't need to do anything for sane-frontends. It has *no* support for infrared, period. For sane-backends, you need a newer version of the code[1], sane-backends-1.0.20 does not have the infrared support yet. It was added in sane-backends-1.0.21. [1] http://sane.alioth.debian.org/source.html After extracting the archive, cd sane-backends-1.0.21/ ./configure CPPFLAGS=-DSANE_FRAME_IR make sudo make install should put an IR enabled epson2 backend and scanimage frontend below /usr/local/. If you do this, it is recommended to remove the Ubuntu libsane package to avoid confusion. After that scanimage -d epson2 -h should be able to tell you what the relevant command-line option is.
