Change to the folder where you downloaded this scanner driver bundle, extract it and install all components with
tar xaf iscan-bundle-1.0.0.x64.deb.tar.gz cd iscan-bundle-1.0.0.x64.deb ./install.sh
in a terminal window.
You will be asked for your password to acquire the privileges needed to install software on your system. This works the same way as with your regular software installation procedure.
This scanner driver bundle contains all components of Image Scan! for
Linux that are needed for the scanner you selected and a convenience
install.sh script. The script can be used to install everything
with a single command.
If you are curious about what the script does, run it as follows
./install.sh --dry-run
That will display the command(s) it will run to install everything.
For a simple help message, try the --help option.
The components in the plugins/ folder are non-free, in the sense
that they do not give you all the freedoms normally associated with
Free Software.
With the exception of the "network" plugin (only included with the
generic iscan-bundle) these plugins are needed for the scanner you
selected. The "network" plugin, however, is optional. If you only
connect your scanner via USB (or SCSI) you do not need it. To tell
the install.sh script that you do not want it installed, use
./install.sh --without-network
The "network" plugin is installed by default because almost all recent EPSON scanners and all-in-ones support access via a (wireless) network connection.
To be completely honest, the GUI of Image Scan! for Linux contains a non-free image processing module as well. It will not work without this module.
While the install.sh script is expected to work as intended in the
vast majority of scenarios it might not work as intended for you. If
that is the case, please pay attention to the error messages in the
output that is produced. That should help you find a workaround by
yourself or in the list below.
This is likely to give messages that include phrases such as are you
root?, Root privileges are required and you need to be root
(possibly in your language). The install.sh script assumes that
you can use sudo to obtain root status. If that is not the
case the install will fail. You can try
su -c './install.sh'
and provide the root password in this case. If you want to use
the --without-network option, make sure to put it inside the
quotes.
Note, however, that many distributions disable root logins these
days and instead set up the first user account created during initial
installation so that it can obtain root status via sudo. If
that is not your account, get the owner of that account to install the
bundle.
There is a small chance that the scanner bundle requires other software to be installed that conflicts with software you have already installed. Before you can install the scanner bundle, you will need to resolve any such conflicts.
The straightforward way is simply to remove any conflicting software that is already installed. Your package manager may suggest ways to resolve the conflict that are less drastic, though.
The install.sh script assumes that you have one of the common
higher level package managers for RPM or Debian packages installed.
It also assumes that the binary packages in the bundle are in the
package format that your distribution expects.
In the unlikely case that no supported package manager is available
you can still install manually using the low-level package managers
rpm or dpkg. First run
./install.sh --dry-run
and note the list of .rpm or .deb files that shows. You can
use the --without-network option with the above command if you
wish. Next, try to install those packages with one of
rpm --install $list_of_rpm_files dpkg --install $list_of_deb_files
This will likely fail due to missing dependencies. In case you used
rpm, then install all of the required packages that are mentioned
in the error output using your regular software installation method
and run the same command again. This time it ought to succeed.
After a failed dpkg, first remove the failed packages.
dpkg --remove $list_of_packages
Note this requires the package names listed at the end of the error
message, not the package files you used to install. Once removed,
you can use your regular software installation method to install any
missing dependencies and run the dpkg --install command again.
Of course, all rpm, dpkg and apt-get invocations require
root privileges. Use sudo or su -c to obtain them.
Very unlikely to happen but if it does, install util-linux and try
again.
