Ok, I misunderstood....
I've xv (useful to build preview icons in pictures directories).
I've seen the black border... And finally, I managed to find who is the
culprit.
The lid of the scanner has a white glossy plastic sheet on foam, it is a
bit small (or slighlty misaligned, I think too small). And what we can
see is the grey plastic frame that support the white sheet...
I think this can explain the problem. I have done more tests with
several white paper sheets stacked. It is better but not 100% yet :
often, the right and left lines are at 2cm apart of the document.
I can survive with this but I will ask Epson if I can have the lid
repaired. But, anyway the lid can move slightly : it is not "heavy
metal" ! As the scanner has still warranty, I think they have to do
that. Ermmm... ;-)
