Gooday again to all
Thanks to all for the effort. After studying what Texstar and others had to say I had a Google and found that Sane-backend-iscan was well featured and giving trouble and that Suse/Mandriva and other OSs had written new rpms. Decided to look at Iscan at www.avasys.jp/english/linux_e/index.html
and the old files of 48 hours earlier had been replaced.with two new ones namely 'iscan-data-1.0.0-2.noarch.rpm', 'iscan-184.108.40.206-1.i386.rpm' and the old iscan-plugin rpm file was still there.
Well into the terminal and install and guess what it did not work. Why? It is necessary to remove the old iscan files from the repository and also 'iscan-backend and saned'. Best to do a reboot and then install the new iscan files in the order as laid out above (ignore the warning after installing the iscan-data rpm) and everything works great.
It was an interesting exercise and I had it up in an hour. Have not had time to return to the Forum since the 24/6.
Again thanks for the ideas Texstar and others.
