Hello Folks,
|
|
<BR>
|
|
<P>I had several problem with color scan with following configuration:
|
|
<BR>
|
|
2.2.16 Kernel
|
|
<BR>
|
|
ncr810 scsi controller
|
|
<BR>
|
|
mustek paragon 1200sp scanner
|
|
<BR>
|
|
sane-packet 1.0.3
|
|
<BR>
|
|
<P>The scanner has a physical resolution of 1200 dpi, color. Black/white and gray
|
|
<BR>
|
|
scanned images work perfect, I have no trouble at all, but when I switch to
|
|
<BR>
|
|
color scan, I have some fancy effect I can not use at all.
|
|
<BR>
|
|
First of all the color dont match with the real ones. The are totally shifted
|
|
<BR>
|
|
into
|
|
<BR>
|
|
blue, green or red. Well not just shifted, that I could correct ...
|
|
<BR>
|
|
The most remarkeable thing about it is, that it is reproduceable and the
|
|
<BR>
|
|
type of the wrong color depends on the used resolution. So scanning at
|
|
<BR>
|
|
120 dpi ist a blue like image without any red scanning with 125 dpi becomes
|
|
<BR>
|
|
more and more green ...
|
|
<BR>
|
|
Additionally I get some "bad lines" in the pictures, they repeat in a constant
|
|
<BR>
|
|
frequent all over the image. If the image is dark, those lines (1-3 pixel
|
|
<BR>
|
|
broad)
|
|
<BR>
|
|
are bright and visa versa.
|
|
<BR>
|
|
<P>Since there are no options in the mustek.conf I tried out so change almost
|
|
<BR>
|
|
everything
|
|
<BR>
|
|
I can. The problem is the same with different types of images, different
|
|
<BR>
|
|
kernels (2.2.14 - 2.2.17)
|
|
<BR>
|
|
and I even plugged a Adaptec 2490 in. All the same error.
|
|
<BR>
|
|
Then I realized, that the scanner is recognized as Mustek 12000 SP and not as
|
|
<BR>
|
|
1200 SP.
|
|
<BR>
|
|
As far as I know the only difference are some cheaper mechanical parts in the
|
|
<BR>
|
|
12000, so I
|
|
<BR>
|
|
dont know if there is something wrong.
|
|
<BR>
|
|
<P>I would be really glad if someone could give me a hint where to look at and
|
|
<BR>
|
|
where to solve that
|
|
<BR>
|
|
problem.
|
|
<BR>
|
|
<P>At last I got another question: I configured saned to scan via network (this
|
|
<BR>
|
|
does not affect the
|
|
<BR>
|
|
problem above in anything - it occurs when scanning on local device and over
|
|
<BR>
|
|
net ...)
|
|
<BR>
|
|
Now I did some "scanimage -dnet:computer:mustek:/dev/scanner ..." which worked
|
|
<BR>
|
|
fine.
|
|
<BR>
|
|
But scanning with the X-frontends like xsane, xscanimage refused with the
|
|
<BR>
|
|
message
|
|
<BR>
|
|
"no device found".
|
|
<BR>
|
|
How can I teach them to use the network - scanner ??
|
|
<BR>
|
|
<P>Thanks for anything that helps me.
|
|

<P>Greetings,
|
