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 ?
Roger.
