<EM>&gt; Hi -- I'm turning here for help -- I've read all the documentation and
</EM><BR>
<EM>&gt; tried everything that I know how to do, and cannot get past this point. I
</EM><BR>
<EM>&gt; have the above configuration and get a &quot;device I/O error&quot; before a scan
</EM><BR>
<EM>&gt; begin every time now. When I first installed this a few weeks ago, I could
</EM><BR>
<EM>&gt; get it to scan 5-10 scans, and then the error would return. Tesing the
</EM><BR>
<EM>&gt; scanner under Windows shows the hardware is OK. I've seen similar issues
</EM><BR>
<EM>&gt; on the newsgroups, but I have not found a solution to it. According to the
</EM><BR>
<EM>&gt; documentation, all my hardware and software is supported and current.
