Lars,
|
|
<BR>
|
|
<P>is the G7000 known by any other name? Is it possible that this is
|
|
<BR>
|
|
the GT-7000 (or Perfection 636)? If that's the case then it
|
|
<BR>
|
|
really should work. This is the scanner that Christian used to
|
|
<BR>
|
|
implement the TPU stuff. I don't have access to a TPU, so I
|
|
<BR>
|
|
can not test this myself.
|
|
<BR>
|
|
<P>If you can provide log files I should however be able to figure
|
|
<BR>
|
|
out what's wrong.
|
|
<BR>
|
|
<P>To turn on logging you have to set an environment variable:
|
|
<BR>
|
|
export SANE_DEBUG_EPSON=128
|
|
<BR>
|
|
This will log _EVERYTHING_ - every byte going from the scanner
|
|
<BR>
|
|
to the backend and the other direction are written to a file,
|
|
<BR>
|
|
so be careful when you set the resolution. Try to limit this to
|
|
<BR>
|
|
50 dpi scans. If the scanner never start to send data however this
|
|
<BR>
|
|
is not a problem.
|
|
<BR>
|
|
<P>BTW: Which version of the EPSON backend are you using?
|
|
<BR>
|
|
<P>This is all under the assumption that your scanner is the
|
|
<BR>
|
|
Perfection 636 (or GT-7000). There are problems with the TPU
|
|
<BR>
|
|
with the Perfection 1200, Epson changed something in the comamnd
|
|
<BR>
|
|
set and I'm still trying to figure out if I can get away without
|
|
<BR>
|
|
having to implement all the new commands.
|
|
<BR>

<P><EM>> Hi,
|

</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> this weekend I found Karl Heinz' mail in the archive and downloaded
|
|
</EM><BR>
|
|
the updated
|
|
<BR>
|
|
<EM>> backend. However, even if he states, that the TPU is supported, I
|
|
</EM><BR>
|
|
cannot use it
|
|
<BR>
|
|
<EM>> on my Epson G7000-photo (SCSI).
|
|
</EM><BR>
|
|
<EM>> I have Sane 1.0.1 and I'm using the latest xsane. When I turn on the
|
|
</EM><BR>
|
|
TPU and
|
|
<BR>
|
|
<EM>> try to scan I get a message like "Invalid parameter". Does anybody
|
|
</EM><BR>
|
|
(Karl
|
|
<BR>
|
|
<EM>> Heinz?) know why it doesn't work?
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> BTW, I'm willing to look for the error myself, but I didn't manage
|
|
</EM><BR>
|
|
to turn the
|
|
<BR>
|
|
<EM>> debugging on. There's some DBG macro which I'm not able to use. How
|
|
</EM><BR>
|
|
do I have
|
|
<BR>
|
|
<EM>> to compile the sources or where do I have to make modifications to
|
|
</EM><BR>
|
|
get the
|
|
<BR>
|
|
<EM>> debugging messages? And where are they put to? I just didn't find
|
|
</EM><BR>
|
|
it.
|
|
<BR>

|
<EM>>
|
|
</EM><BR>
|
