Thanks for that suggestion, Kare.

I had not heard of Skanlite, but found it OK in Synapt & installed it - 
only version 0.7-2ubuntu3 in my Ubuntu 11.10 though.
I will try 0.8 when I upgrade Ubuntu to 12.04, but that will not be for 
several months yet (deliberate late adopter to avoid teething troubles).

Even this version successfully keeps general settings (format & quality, 
save-to-location etc) which is better than iscan at the moment in this 
respect.

Tone correction was not good though,  for several reasons, at least on 
first attempt (please correct if mistaken):
1. Corrections don't appear simultaneously in the preview display, so 
you have to stab in the dark then make another preview to see the result.
2. After correction (+10% brightness & +10% contrast could be about 
right) then impossible to select the scan area for a document, which 
then appears as numerous fragments...
3. Correction settings not retained (in this version).

Another problem is that the only dpi options are 300/2400/4800dpi, so 
only 300dpi really for routine-size scans.
This is another subject, already open, but not fixed, here:
http://lists.alioth.debian.org/pipermail/sane-devel/2012-April/029713.html

Overall, no scanning application I have tried yet in Ubuntu could get 
even an 'acceptable' rating for this scanner, which is not really old or 
exotic, is it.
Pity...

Thanks again for the suggestion!
