Hi Doug,
<BR>
<P>I found nothing unusual in the protocol listing. So I would like you to
<BR>
do some more tests with the tool hpscan. Please pick up an updated
<BR>
version from my homepage.
<BR>
I had a look into the SCL-documentation about the XPA. When scanning
<BR>
with an XPA, the first 1.75 inch of the flatbed are used as calibration
<BR>
area. Thus they can not be scanned. This could be the reason for a
<BR>
limited scan area. Please try a XPA scan with the tool hpscan by
<BR>
<P>hpscan &lt;device&gt; -otyp 5 -dwidth 24 -invdata -xres 50 -yres 50 -output
<BR>
xpa.ppm -xpa 0 -xpascan 0
<BR>
<P>The output PPM-file is xpa.ppm. You should play around with the
<BR>
following command line options:
<BR>
<P>-xpa &lt;num&gt; : enable (0)/disable (1) XPA
<BR>
-calarea &lt;y&gt; : start of calibration area -1: cal. on white strip, &gt;=0
<BR>
y-coordinate
<BR>
<P>You can also use
<BR>
<P>hpscan &lt;device&gt; -qxpastat
<BR>
hpscan &lt;device&gt; -qxpardy
<BR>
<P>to inquire the status of the XPA.

<EM>&gt; Hi Peter,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Here's your requested hp.lis file.
</EM><BR>
<EM>&gt; Detailed info:
</EM><BR>
<EM>&gt; - HP scanjet 6300C
</EM><BR>
<EM>&gt; - Transparency adapter
</EM><BR>
<EM>&gt; - No document feeder present.
</EM><BR>
<EM>&gt; - 'cat /proc/scsi/advansys/0' attached
</EM><BR>
<EM>&gt; - xscanimage set with 'colour', '300dpi', 'XPA'
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I do get an output file however it is mostly black with grey/white 'snow'. Yesterday it was a black with white diagonal lines output, but not the image of the photo negative on the scanner bed.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; It did wait for approx 30 seconds before it actually scanned after I pressed the software scan button. Is that normal?
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Thank you for your help.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Doug
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; ps. For the first time, the scanner just turned it's lamp off by itself. hmm. I guess about 15 mins as I wasn't timing it. It's still good to have the backup hpscan.
</EM><BR>
