'footnote gentoo-sane On Gentoo the package is [`sane-backends`], as per the [url https://wiki.gentoo.org/wiki/SANE wiki].
Sometimes your Epson scanner might work out of the box, and sometimes it might not.
First, make sure you have [url http://sane-project.org/ SANE] installed on your machine[$gentoo-sane].
Second look through [url http://www.sane-project.org/sane-mfgs.html#Z-EPSON the website], most scanners are supported out of the box, but about 15% of them either aren't supported or are untested.
## Complete or Good
'footnote openrc-sane For OpenRC: [`rc-service saned status`]
If your scanner falls into the first category, labeled "Complete" or "Good", you probably have an issue with SANE.
Make sure the [`saned`] service is running without errors[$openrc-sane]:
```bash
systemctl status saned.service
and make sure the [url http://www.sane-project.org/man/sane-epson2.5.html sane-epson2] (or [url http://www.sane-project.org/man/sane-epson.5.html sane-epson]) back-end is enabled, you should have [`epson2`] (or [`epson`]) without a leading [`#`] inside [`/etc/sane.d/dll.conf`].
## epkowa plus non-free interpreter
If it's unsupported and there is a note
.quote supported by the epkowa backend plus non-free interpreter
you can still make it work.
You'll have to get the [=non-free=] (free as in [url https://en.wikipedia.org/wiki/Free_software_movement publicly available source code], you don't have to pay for anything) Epson Scan 2 software.
It can be downloaded from [url https://support.epson.net/linux/en/epsonscan2.php the support site] as a [`deb`] or [`rpm`] package.
If your system doesn't natively work with any of those (i.e. it isn't listed under "Distribution" and isn't some sort of derivative of those), you can still try the [`rpm`] package.
:ordered
1. Install [`rpm`] with your package manager
2. Download the 32 or 64 bit [=[ rpm ]=] package
3. Extract it
```bash
tar -xf epsonscan2-bundle-SOMETHING.rpm.tar.gz
4. Install the core application and non-free plugins with rpm
```bash
sudo rpm -Uvh --nodeps ./epsonscan2-bundle-SOMETHING.rpm/core/epsonscan2-SOMETHING.rpm ./epsonscan2-bundle-SOMETHING.rpm/plugins/epsonscan2-non-free-plugin-SOMETHING.rpm
Alternatively, you can install the [`deb`] package with [`dpkg`] or build and install it from [url https://download.ebz.epson.net/man/linux/epsonscan2_e.html#sec5-1-4 source] (source file is available at the bottom of the [url https://support.epson.net/linux/en/epsonscan2.php support site]).
'footnote gentoo-epkowa Surprisingly enough, on my Gentoo installation everything works fine without the package. Either something else is helping me or [url http://www.catb.org/jargon/html/magic-story.html something is in the "more magic" position]...
You will need[$gentoo-epkowa] to install [`iscan`], which usually provides the aforementioned [`epkowa`] backend.
Also make sure you have [`epkowa`] inside [`/etc/sane.d/dll.conf`] without a leading [`#`].
Finally, only for the very first time after connecting your powered-on scanner, start "Epson Scan 2", select it and press "Next".
The drivers should automatically be installed and you can close the window and use your own scanning software of choice afterwards.
