Hi<br>
<br>
<br>
in order to notice the lines let me describe them a little more.<br>
<br>
<br>
the green lines are very very light,  mostly seen in white/clear zones of the image, not so much on dark ones. and they are always on the left side of the image, at about 1 cm from the left margin. they go from top to bottom of the scan.<br>
<br>
<br>
At least this is how i see them :-P (hope is not only a paranoia of mine :-D )<br>
<br>
<br>
i've enabled debugging as instructed and created 5 new scans with the command posted. Some of the scans, (number 2 and 4) are mostly white, in order to see the issue in more detail.<br>
