As Pilot6 said, you need to go to the Epson Drivers Site, 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
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.
