If your scanner is older and does not work, follow the instructions on the Arch Linux wiki:

https://wiki.archlinux.org/title/SANE/Scanner-specific_problems#Epson

And, if you have one of the scanners listed below, install the "epsonscan2-non-free-plugin" package.

It contains firmware necessary for your device.

• GT-X830
• Perfection V19
• Perfection V19II
• Perfection V33 / GT-S630
• Perfection V37 / GT-S640
• Perfection V39 / GT-S650
• Perfection V39II / GT-S660
• Perfection V500 / GT-X770
• Perfection V330 / GT-F730
• Perfection V370 / GT-F740
• Perfection V550
• Perfection V600 / GT-X820
• WorkForce GT-1500 / GT-D1000

The non free plugin is not only for OCR or Wireless scanning, some models do need a proprietary firmware! Here is a list of models that need the non free plugin, get the device id through lsusb

@vitaliikuzhdin: The website in the “url” field contains the link to download the source code, which is necessary for other users to validate PKGBUILD.

The Arch Wiki documentation mentions this about the variable:

The URL of the official site of the software being packaged.

https://wiki.archlinux.org/title/PKGBUILD#url

The website provided by Epson includes the following information:

Epson Scan 2

This package contains all essential software to use your scanner.

https://support.epson.net/linux/en/epsonscan2.php

The user manual, which comes with the scanner or MFP, explains more about the software. That's Epson's decision.

And it doesn't make sense to link to a page with various command-line options for a GUI tool.

For the above reasons, I'll keep the URL as it is now.

There is no information that it needs to contain a more descriptive page.

The website provided by Epson is not instructive, but that's the company's fault.

And it makes no sense to link to a page with various command-line options for a GUI tool.

@Lehmeier, because url="" is a string literal, not an array. Why would the user even need a download page if the PKGBUILD is supposed to manage the sources for them?

Why not offer both? You can do one thing and not do the other.

Might be useful to change the upstream URL to https://download.ebz.epson.net/man/linux/epsonscan2_e.html. Providing just the download page isn’t very helpful, but linking to a somewhat informative guide could be better.

compiling the latest version (with locally added patch from @psheng) went well and epsonscan2 works great!

I don't understand why the maintainer didn't include the (obviously) needed patch?

UPDATE: Resolved in v6.7.70.0-4

I get the following error when building the package:

@Psheng

I can confirm that your github clone with those patches is working great! App starts without any complain and finds my scanner (previous installs before this startup error didn't so they added old scanners)

App seems to be working well although not fully tested jet
