it's definitly not a SANE bug - it's a problem in fine calibration - if the position
of the fine-calibration strip is not excactly set, you might get those stripes - some
backends tryy to find it automagically, some set them directly.
For the plustek-backend, you might want to test with various values for
posShadingY (to set in the options section in plustek.conf), try values from 10 to 50...
and make sure to use the latest CVS snapshot - enable debug and try a scan, i.e.:
export SANE_DEBUG_PLUSTEK=19 ; xsane - send us the output.
