Moving on ... it is possible to get .deb packages from Avasys by downloading the tar file. Trouble is that when I try to install, it requires a package called sane-backend which does not exist in Package Manager. In addition, it requires that sane is itself installed from a tar - which means uninstalling it and re-installing a tar version for this. Error messages from my initial attempt to install without doing the above, indicated that sane-backend was missing. Googling this got me to the Sane project website (http://www.sane-project.org/sane-backends.html
) which had links for the Epson 3490 to Epson (dead-end) and it was not easy to understand what to download from where? Even if this could be made to work, surely it might stop working if I do certain downloads using Package Manager again! So I have decided to abandon trying to install Avasys software as this is too complicated and try to find another solution.
So I found an Ubuntu forum and adapted some advice there and the scanner now functions with both Flegita (scanner utility) and Xscan. Phew !!!!
1) It is a good idea to have the following packages are installed (use Package Manager):-
2) Install the Epson scanner under Windows and find file: esfw52.bin from the installation directory (C:WINDOWS\system32 ?) or extract it from a cab on the Epson drivers CD.
3) On Linux as root:-
if snapscan directory does not exist, then create it:-
4) Copy file esfw52.bin to the snapscan directory. Remember both directory
and file must be owned by root.
5) As root, edit /etc/sane.d/snapscan.conf and replace the firmware directory in the first lines with /usr/share/sane/snapscan/esfw52.bin. Save and close the file.
6) Log out of root and in as your normal user.
7) The scanner should now work with both Flegita and Xsane.
