<EM>> Hello,

|

<EM>> I spend some time to play with my Phantom 330 CX (FW 1.26) and the
|
|
</EM><BR>
|
|
<EM>> pre0.9-version
|
|
</EM><BR>
|
|
<EM>> of the microtek2 backend (thanks to Bernd, who is fighting the strange
|
|
</EM><BR>
|
|
<EM>> behavior of the various types!). Here's the story:

|
|
<EM>> I'm using ppscsi 0.91, sane 1.00 with the upgrade patch to 1.01 and the

|
|
<EM>> microtek2-pre0.9.020100 backend.
|
|
</EM><BR>
|
|
<EM>> I am able to scan, but there are three points:
|
|
</EM><BR>
|
|
<EM>> -the option --backend-calibration=yes doesn't seem to work, (I can't

|
</EM><BR>
|
|
<P>Yes, this option is not effective for that model. The calibration for
|
|
<BR>
|
|
the 330cx is different from the calibration process on other models.
|
|
<BR>
|
|
<P><EM>> hear the typical noise that the scanner makes under windows) and the
|
|
</EM><BR>
|
|
<EM>> fine vertical stripes that were mentioned before in this mailing list
|
|
</EM><BR>
|
|
<EM>> are there.
|
|
</EM><BR>
|
|
<EM>> -the image is horizontally mirrored (the preview also is)
|
|
</EM><BR>
|
|
<P>Yes, that is a known problem. I will see whether I can fix it in the near
|
|
<BR>
|
|
future. Grayscale and B/W scans, however, should not have this problem.
|
|
<BR>
|
|
<P><EM>> -when the scan is performed, the head turns back into starting positon,
|
|
</EM><BR>
|
|
<EM>> but it doesn't stop. The motor drives the head approx. 20 seconds
|
|
</EM><BR>
|
|
<EM>> against the stop, then the head returns to its normal starting position.
|
|
</EM><BR>
|
|
<EM>> If I did a scan under windows before and didn't switch off the scanner
|
|
</EM><BR>
|
|
<EM>> in the meantime then the behaviour is normal, the head stops right at
|
|
</EM><BR>
|
|
<P>This is interesting, because it is the first time, that I read, that
|
|
<BR>
|
|
a scan with this model does not show this strange behaviour (hitting
|
|
<BR>
|
|
the top or bottom of the scan area). The backend does not execute one
|
|
<BR>
|
|
SCSI command for this model, that is executed, when other models are
|
|
<BR>
|
|
connected. This command fails on the 330cx for whatever reason, and
|
|
<BR>
|
|
I suspected that this missing command might cause these problems.
|
|
<BR>
|
|
When the scanhead stops at the right position after a scan under windows
|
|
<BR>
|
|
this shows, that the missing command is probably not the cause.
|
|
<BR>
|
|
<P><EM>> the stop and goes into starting position. Starting only the Twain driver
|
|
</EM><BR>
|
|
<EM>> has no effect, only if a scan was performed the problem is fixed.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> I was able to get the scanner to work with wine (with scantest and with
|
|
</EM><BR>
|
|
<EM>> PaintShopPro) and to log some ASPI traces. So, Bernd, if you are
|
|
</EM><BR>
|
|
<EM>> interested in logfiles, let me know what information you need. For now,
|
|
</EM><BR>
|
|
<EM>> I did an "wine /dos/Programme/psp/psp.exe -debugmsg +aspi 2>wine.log".
|
|
</EM><BR>
|
|
<P>These debug options are just fine. Can you make such a trace available,
|
|
<BR>
|
|
from the first scan after the scanner is switched on ? Can you also
|
|
<BR>
|
|
trace a scan (also immediately after the device is powered on) with
|
|
<BR>
|
|
sane ? The 'option dump 2' should be set in the microtek2.conf file.
|
|
<BR>
|
|
This will trace the SCSI commands, that the backend issues, so that we can
|
|
<BR>
|
|
compare them.
|
|
<BR>
|
|
<P>However, there is one drawback of the wine traces. wine traces only the
|
|
<BR>
|
|
SCSI commands, but not the parameters of the commands, and not the
|
|
<BR>
|
|
replies from the device, so I cannot say, whether it will be sufficient.
|
|
<BR>
|
|
Otherwise wine must be patched (I have a patched version of the 990704
|
|
<BR>
|
|
release).
