<EM>&gt; Hi,

<EM>&gt;
</EM><BR>
<EM>&gt; EPSON GT-8000...
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I try
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; # scanimage -d epson --mode color &gt;scan.log 2&gt;&amp;1
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; And the scanner fault...
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; # [epson] code f2
</EM><BR>
<EM>&gt; # [epson] error, expected STX
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; What's the meaning of STX ?
</EM><BR>
<P>That's part of the EPSON communication protocol: When the scanner
<BR>
sends STX as an acknowledge message then it has more data to
<BR>
transmit. A command that does not produce any scanner data is
<BR>
answered with ACK (set resolution will only send ACK to let
<BR>
the software know that it was able to set the resolution),
<BR>
get identity will send information about the scanner, so it
<BR>
will first send STX, which also means that the length of
<BR>
the data block is transmitted after the STX.
<BR>
<P>0xf2 is something the scanner will never produce as return code,
<BR>
this again is an indication for SCSI problems (as I suggested
<BR>
before). Unfortunately I don't have access to any flavour of
<BR>
BSD so I can not test this myself. Is anybody on this list
<BR>
using an EPSON SCSI scanner with BSD?
