Linux Scanning with an Epson Printer

2023-01-19 2

This will be simpler than the brother printer as we won’t be configuring anything on the network. The Epson ES-400 doesn’t have a wireless option so it must be plugged in via usb.

https://www.amazon.ca/dp/B08P3YVH3X (349.99 @ Jan 19 2023)

Once the scanner is plugged in via usb, we just need to install the Epson driver and away we go! These instructions are for CentOS 7.4 specifically.

Get the driver:

wget https://download2.ebz.epson.net/epsonscan2/common/rpm/x64/epsonscan2-bundle-6.7.0.0.x86_64.rpm.tar.gz

This will download a tarred file which I wasn’t able to get it to install via rpm. Instead you can untar the file and run the install script directly.

tar xvf epsonscan2-bundle-6.7.0.0.x86_64.rpm.tar.gz
cd epsonscan2-bundle-6.7.0.0.x86_64.rpm
./install.sh

This will install the Epson driver.

Now we can run scanimage -L:

[root@localhost ~]# scanimage -L
device `epsonscan2:123:123:ES0231:425' is a EPSON ES-400II:001:005 flatbed scanner

Now we can load a page and give it a shot:

scanimage --format tiff -d "epsonscan2:123:123:ES0231:425" > image.tiff

With that we are done! We can now use a Epson scanner connected via usb to a Linux machine.

You can get device specific options by:

scanimage --help -d 'epsonscan2:ES-400II:123:123:ES0231:385'
