<P><EM>&gt; I'm not shure, perhaps is my problem similar with the Snapscan 600
</EM><BR>
<EM>&gt; too. I can get no scans with resolutions over 300 dpi with the
</EM><BR>
<EM>&gt; transparency-unit. What do you think, Sébastien, are your changes
</EM><BR>
<EM>&gt; for me too?
</EM><BR>
<P>Hi,
<BR>
<P>could you explain more precisely : &quot;I get no scans with resolutions
<BR>
over 300dpi with the transparency unit&quot;? Does it block while scanning?
<BR>
Is it specific to the transparency-unit? Does your scanner normally
<BR>
supports &gt;300dpi?
<BR>
<P>The changes I made are very small indeed.
<BR>
1. in snapscan.c : corrects a problem because my scanner can't works
<BR>
with &quot;non-blocking&quot; mode.
<BR>
2. in snapscan-scsi.c : corrects a problem where the picture becomes
<BR>
full of noise after a few lines
<BR>
3. in snapscan-source.c : corrects a problem where the scanner blocks
<BR>
itself with quite big color pictures in high resolution (300dpi in my
<BR>
case)
<BR>
<P>You can find how I corrected those bugs by looking for ACER300F in
<BR>
each file. If your model has one of those problems (in your case that
<BR>
may be problem 3), you have to put the string corresponding to your
<BR>
model in the &quot;if&quot; test instead of ACER300F (in your case probably
<BR>
SNAPSCAN600).
<BR>
<P>Then if it solves your problem please tell us, so we can add it in the
<BR>
source for people with the same scanner.
<BR>
<P>I will make a snapscan-29102000.tar.gz at the same place for 1236s
<BR>
models (since someone asked for it) tonight (GMT+2).
<BR>
<P>bye
<BR>
