Your log might just be the little bit of info the community > needs. Well, I've tried to. But guess what - I cannot make the thing misbehave at all now ! I have: Restored (all sets of) factory defaults on the printer; Uninstalled all the things in the following list (i.e. the total list of what I had installed), working up from the bottom (and reinstalling sane-backends-drivers-scanners and sane-backends-libs after taking out sane-backends-devel - but I checked the version was the same as it always has been); (This is the list of what I had installed since it wouldn't work: libtool-ltdl-2.4.2-20.el7.x86_64 (was already there) (updated to) 2.4.2-21.el7_2.x86_64 libtool-ltdl-devel-2.4.2-21.el7_2.x86_64 atkmm-devel-2.22.7-3.el7.x86_64 cairomm-devel-1.10.0-8.el7.x86_64 glibmm24-devel-2.42.0-1.el7.x86_64 gtkmm24-devel-2.24.2-8.el7.x86_64 libsigc++20-devel-2.3.1-4.el7.x86_64 pangomm-devel-2.34.0-3.el7.x86_64 sane-backends-1.0.24-9.el7.x86_64 sane-backends-devel-1.0.24-9.el7.x86_64 sane-backends-drivers-cameras-1.0.24-9.el7.x86_64 sane-backends-drivers-scanners-1.0.24-9.el7.x86_64 imagescan-3.20.0-1epson4centos7.x86_64.rpm imagescan-plugin-ocr-engine-1.0.0-1epson4centos7.x86_64.rpm imagescan-plugin-networkscan-1.1.0-1epson4centos7.x86_64.rpm ) Removed the net line from epson2.conf, and added a usb line in its place with the same numbers as before; Simultaneously powered down both computer and printer/scanner; Unplugged the network cable from the printer and plugged in a USB cable instead. And it just will not misbehave ! Alternatively, it may be because the good software has made some change in settings to the scanner which aren't reverted by "restore factory defaults". Any ideas on what's going on ?

It provides downloads for: - Image Scan! for Linux (provides epkowa backend) - Image Scan v3 (provides imagescan backend) These aren't the same thing and both cater to different sets of scanners. I would assume that Andrea's scanner is supported via Image Scan! for Linux which includes a SANE epkowa backend. The Image Scan v3 bundle includes a SANE imagescan backend. # BTW, Image Scan v3 is a "corporate" rebrand of the Utsushi software # that I mentioned in an earlier post. Utsushi provides an utsushi # backend which, to all intents and purposes, is the same. > instead it seems to use something at > /usr/lib64/sane/libsane-imagescan.so.1, despite the fact that > /etc/sane.d/dll.conf doesn't contain any line enabling that backend. Quite a few distributions also implicitly include the snippets below /etc/sane.d/dll.d/ as if they were part of /etc/sane.d/dll.conf. Both Image Scan v3 and Utsushi install the configuration file snippets there, IIRC. Not sure anymore about Image Scan! for Linux. # I've been intimately involved in the development and maintenance of # all three for a long time. However, as of April 2016 I am no longer # involved any only keep Utsushi somewhat in sync with Image Scan v3. > So I don't entirely understand why it works, but I'm glad that it > does! > >> I didn't try it with xsane, but you should be good to go. > > Thank you - it works fine with xsane also. Please note that support for network attached devices with the imagescan (or utsushi) backends relies on a non-free plugin. This is despite the fact that Epsons's Software License Agreement makes you believe the whole package/bundle is GPLv3. # I'm off complaining about that now ...

[sane-devel] Thank you for help driver CanoScan N656U
I compiled Sane 1.09 on my Linux Red Hat 8.0 live machine and it worked perfectly with my CanoScan N656U scanner. I didn't expect it to be so easy, especially on a platform that doesn't get a whole lot of attention sometimes. Thank you SANE developers! Maurizio Tiecher
[sane-devel] Thank you!
I compiled Sane 1.09 on my Linux PPC (YDL) machine and it worked perfectly with my old Relisys Scorpio scanner. I didn't expect it to be so easy, especially on a platform that doesn't get a whole lot of attention sometimes. Thank you SANE developers! Drew
