I installed the driver for Epson Perfection V600 Photo: iscan-data_1.13.0-1all.deb as well as iscan_2.28.1-3.ltdl7_i386.deb.
But the scanner does not work. How can I install the scanner drivers?
I installed the driver for Epson Perfection V600 Photo: iscan-data_1.13.0-1all.deb as well as iscan_2.28.1-3.ltdl7_i386.deb.
But the scanner does not work. How can I install the scanner drivers?
Note: See my other answer for latest Ubuntu steps: https://askubuntu.com/a/1135180/8570
Looks like a package is missing but I will detail the whole process to help other users.
Search for the Epson Driver site for Perfection V600 Linux drivers:

Download the relevant packages from both links:
iscan-data_1.24.0-2_all.deb
iscan_2.29.2-1~usb0.1.ltdl7_amd64.deb
iscan-plugin-gt-x820_2.2.0-1_amd64.deb
Notes:
ltdl3 instead of ltdl7i386 instead of amd64Install the packages as per the order above by double-clicking on the package to open it with the Ubuntu Software Centre. Alternatively use dpkg -i <deb> from the terminal for each package.
Connect and power on the scanner.
Open Dash and search for Image Scan! for Linux
It sometimes can take a while for the software to open, so be patient, and eventually it should find your scanner and you are ready to scan.
References:
Epson released an updated combined install package which can be obtained via their support site.
Search for V600, choose Linux operating system and downloading all-in-one driver package.
Epson provide notes on how to install but the quick overview is to run the following in the terminal that will extract and start the installation process:
tar xf iscan-gt-x820-bundle-1.0.1.x64.deb.tar.gz
cd iscan-gt-x820-bundle-1.0.1.x64.deb
./install.sh
Normally this would be enough but at the time of writing April 2019 iScan opens with this error message:
Could not send command to scanner. Check the scanner’s status.
So additional steps are required. These have been taken from bug #1728012.
Create a rules file so that the USB scanner has permission to be used by user without needing sudo.
sudo vim /etc/udev/rules.d/79-udev-epson.rules
Paste this line into the new rules file:
ATTRS{manufacturer}=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="*", MODE="0777"
As mentioned in the bug report the libsane-epkowa drivers are not being found so create a link to them in the correct location:
sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane
Some commands to check if your scanner can be found. I have included the output with working Epson V600 scanner.
Check if your scanner device can be found:
$ scanimage -L
device `epkowa:interpreter:001:010' is a Epson (unknown model) flatbed scanner
Find any scanner attached to the computer (without superuser privileges). To identify USB permission issues.

For Ubuntu 18.04 you can install Epson Perfection V600 Photo scanner (tested that works on January 2023). This is an all-in-one software for Linux, released on December 2022 by Epson. You can download epsonscan2-bundle-6.7.0.0.x86_64.deb.tar.gz from here: https://support.epson.net/linux/en/epsonscan2.php
This gets installed without issues, however all color scans are dominated by a bright green overlay. The older all-in-one software, iscan-gt-x820-bundle-2.30.4.x64.deb.tar.gz (available from here:https://support.epson.net/linux/en/iscan.php?model=gt-x820&version=2.30.4) gets installed and works without issue.
If the iscan options to save the scanned file as a .png or .jpeg are greyed out, install libpng12-0_1.2.54-1ubuntu1.1_amd64.deb from this site: https://launchpad.net/~ubuntu-security/+archive/ubuntu/ppa/+build/15108504, if you have issues with .png files, and libjpeg62 if you have issues for .jpeg files.
You need to go to the EPSON Download Center, search for your model and download the driver.
The drivers depend on libsane. However, in Ubuntu 23.10, the package libsane is missing. A workaround is to download and install the libsane package from another Ubuntu release. In the example below, I am using libsane from Ubuntu 23.04 (Lunar Lobster) for amd64 architecture. You also have to install libsane1 package, because libsane depends on it.
sudo apt install libsane1
wget http://mirrors.kernel.org/ubuntu/pool/universe/s/sane-backends/libsane_1.2.1-1_amd64.deb
sudo dpkg -i libsane_1.2.1-1_amd64.deb
After that, you should be able to install your drivers with Running sudo ./install.sh from within the driver's directory.
Epson Perfection V600 Photo, after plugging in & turning on, is recognized by Ubuntu > Info Center > USB Devices, but neither Skanpage or Skanlite can find the scanner.
I used this link to find a driver & software:
http://download.ebz.epson.net/dsc/search/01/search/

I downloaded the Epson Scan 2, version 6.7.70.0, dated 10-31-2024, for my 64bit system and installed it
tar xf epsonscan2-bundle-6.7.70.0.x86_64.deb.tar.gz
cd epsonscan2-bundle-6.7.70.0.x86_64.deb
./install.sh
The application, Epson Scan 2, took a few moments to recognize the scanner, but after that, the scanner worked well on a test document. Note that this is, supposedly, the same version of Epson Scan 2 that gave me a 'bright green overlay' on all scanned documents when installed on Ubuntu 18.04.
