Hi,
|
|
<BR>
|
|
<P>Glad to see that you and some other folks are working hard on the
|
|
<BR>
|
|
snapscan backend.
|
|
<BR>
|
|
<P>I have similar problems to what is reported here. The scanner I have is
|
|
<BR>
|
|
called
|
|
<BR>
|
|
AcerScan (Prisa) 610ST It is a SCSI model with a built-in transparency
|
|
<BR>
|
|
module.
|
|
<BR>
|
|
My understanding is that the differences between models are something
|
|
<BR>
|
|
like this:
|
|
<BR>
|
|
<P> 8/24 bit 10/30bit 12/36bit 12/48bit
|
|
<BR>
|
|
DPI ________________________________
|
|
<BR>
|
|
300 | 300 310 320 340
|
|
<BR>
|
|
600 | 600 610 620 640
|
|
<BR>
|
|
<P>I would also note that the Vendor ID string for my model is:
|
|
<BR>
|
|
FlatbedScanner_4
|
|
<BR>
|
|
This is odd because in the snapscan.h header file it seems to indicate
|
|
<BR>
|
|
that
|
|
<BR>
|
|
FlatbedScanner_4 is the vendor ID for the VUEGO310S.
|
|
<BR>
|
|
The VUEGO610S should be FlatbedScanner_2.
|
|
<BR>
|
|
Also, the Vuego and Prisa names seem odd. Perhaps this is a difference
|
|
<BR>
|
|
between Agfa and Acer models, but my scanner is clearly marked Prisa,
|
|
<BR>
|
|
even though it is 10-bit model.
|
|
<BR>
|
|
<P>I have installed sane-1.0.3 Redhat 7 rpms and source code, and also have
|
|
<BR>
|
|
sane-1.0.1 sourcecode.
|
|
<BR>
|
|
<P>Any suggestions on what I can do to resolve these issues? I am trying to
|
|
<BR>
|
|
make sense out this so we can have support for all of the snapscan
|
|
<BR>
|
|
models instead of just a few. I will try to apply your patch today as
|
|
<BR>
|
|
is, and see of it works. If not, maybe we can work out how to modify it
|
|
<BR>
|
|
to cover 610s models as well as 310s models.
|
|
<BR>
|
|
<P>Thanks much,
|
|
<BR>
|
|

|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Your scanner probably can't go that high.
