 I experienced a similar problem (besides some others)<br>
 when writing the backend for the ScanExpress models.<br>
 The reason for this problem was that the scanner does<br>
 not start necessarily with a red line on each read<br>
 (depending on resolution, buffer size). <br>
 <p>
 Maybe the line distance code for the SE works even<br>
 for your scanner, so try the following:<br>
 <p>
 Get the pre-1.00 of SANE, change in output_data (file backend/mustek.c)<br>
 <p>
   if (s-&gt;hw-&gt;flags &amp; MUSTEK_FLAG_SE)<br>
      num_lines = fix_line_distance_se (s, num_lines,<br>
      bpl, data, extra);<br>
 <p>
 to<br>
  <br>
   s-&gt;ld.peak_res = SANE_UNFIX(s-&gt;val[OPT_RESOLUTION].w);<br>
   if ((s-&gt;hw-&gt;flags &amp; MUSTEK_FLAG_SE) || 1)<br>
      num_lines = fix_line_distance_se (s, num_lines,<br>
      bpl, data, extra);<br>
 <p>
 recompile, install ... <br>
 <p>
 But use *ONLY* scanimage, and with a resolution of 75, 150, 300, 600dpi.<br>
 Otherwise your system will certainly<br>
 crash!<br>
