Hi,
first of all, thank you for the excellent work you´ve done to make the
SCANEXPRESS working with
sane. And all the other guys for developing the SANE software, too.
Are you interested in other cases of misalignement of red lines?
My configuration (ASUS SC200 with 3 SCSI dsks, 1 CDROM and the Scanexpress
on a single cable) shows the same effect with resolution >300 dpi
Bye
