[sane-devel] Scanner Epson Perfection 1250 Photo on Ubuntu Lucid 10.04

[Françoise Del Socorro]

Thank you both,


Indeed scanner works perfectly in command-line even after deleting (with 
Computer Janitor) iscan, imlib and iscan-plugin. (With Wine, they happen to be a 
software like Xsane, so Iscan is the driver + software pack that is only 
compatible with a few RPM distros, and libsane (plustek) + sane-utils 
(scanimage) is the driver + software pack compatible with DEB distros and 
perhaps also RPM.)

But this scanner isn't working with graphical user interface softwares like 
simple-scan nor xsane because plustek is not selected, even if Xsane ask us to 
select it at start. So is there a way to load modules automatically into scanner 
softwares?

And is there a way for it to work faster ? (or perhaps old scanners are > 
180s/page)

-> more than 3min, huge size: 10 156 x 14 028 pixels, resized with GIMP.

that's perfect, as it's the default setting for scanimage.
Either use a suitable frontend like xsane for adjusting the scan area
or use the -x -y parameters for scanimage to enlarge the scan area.
You might also adjust the resolution.

"man scanimage" might be your friend.
