That page no longer exists.  Please download Image Scan! for Linux
packages via

  http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX

Have a look at the FAQ for which packages you need to install at

These packages are old and miss the non-free plugin needed for the V10.
You need the following Debian packages for your architecture

  iscan_2.29.1-5
  iscan-data_1.19.0-1
  iscan-plugin-gt-s600_2.1.2-1

The epson2 backend (in its default setup) is known to cause long delays
in device recognition and occasionally prevent the epkowa backend from
doing its job.  Try disabling it.

This should not be necessary.

When you install iscan from binary packages it automatically enables
itself.  When you install the plugin package, it automatically adds
itself to the list of supported devices.  There is *no* needs to do
anything but install the required packages.  Things should work out of
the box.

Hope this helps,
