<EM>&gt; &gt; &gt; &gt; all other scanning modes seem to work fine, but when scanning color,
</EM><BR>
<EM>&gt; &gt; &gt; &gt; horizontal banding appears. when scanning nothing, the results are cyan
</EM><BR>
<EM>&gt; &gt; &gt; &gt; bands with white lines between them.
</EM><BR>
<EM>&gt; &gt; &gt; &gt;
</EM><BR>
<EM>&gt; &gt; &gt;
</EM><BR>
<EM>&gt; &gt; &gt; Can you try the latest snapshot ?
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; just did. same result. heres a sample.
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Looks not like a backend problem. For problems with communications, the
</EM><BR>
<EM>&gt; image should look even more worse.
</EM><BR>
<EM>&gt; Do you see any mechanical problems ? Does the scan head move over the
</EM><BR>
<EM>&gt; image in a single pass, not moving forward and backward ?
</EM><BR>
<P>it moves in a single pass after a few movments near the top which seem to be
<BR>
some kind of initialization. the banding problems also appear in greyscale, did
<BR>
not
<BR>
notice them since they dont show up in the preview.
<BR>
<P>i remember the scanner working fine on another machine (running NT and
<BR>
photoshop)
<BR>
ill try again on that one and on irix with sane 1.0.1
