Hello !<br>
<p>
I had a similar effect with lost lines at equal distances when I<br>
implemented my backend (coming soon) for the Paragon 600 II N.<br>
My explanation for this:<br>
<p>
The fix_line_distance() function loses data when it is called<br>
multiple times with a stripe of given height each time.<br>
Possibly, this does only apply to the fix_line_distance_normal()<br>
function and only if the scanner does not already correct it.<br>
<p>
Also to say, the stripes only happened in color mode, not in<br>
grayscale mode.<br>
<p>
It's well possible that I'm wrong and that your problem is rather<br>
related to the SCSI part of the implementation.<br>
<p>
Regards,<br>
<p>
Andreas.<br>
