here is the log: <a moz-do-not-send="true"

looking at it, i found this:<br>
<code> <br>
[genesys] Calibration filename set to:<br>
[genesys] >/home/niky/.sane/plustek-opticbook-3600.cal<<br>
[genesys] read_calibration: enter<br>
[genesys] Calibration: Cannot open
/home/niky/.sane/plustek-opticbook-3600.cal<br>
[genesys] read_calibration: exit<br>
[genesys] sane_open: exit<br>
</code><br>
which explains why the colors are not as expected, doesn't it?<br>
however, i am not sure what to do with that... i'll have to see if
they have some king of calibration sheet or something, but i don't
think so i mean, some people are working with this scanner on
windows, and they just installed the software and that's all. <br>
<br>
anyway, the image looks pretty much the same (again, converted to
jpg, this time without the -quality flag for imagemagick )<br>

looking at the rest of the log, i see many things but understand
very little (i see what looks like many calls for scan, and then
many many more for ccm filtering... whatever that means). however,
as you see at the end it give exactly the same message (last four
lines or so). <br>
<br>
ok. so, now i have the debug log, but i don't know what to do with
it. any clue for me?<br>

and the second one is a (low quality) photo of it
(taken with my cell phone). keep in mind it gives
very little contrast - the light part is actually
white. <br>

i have been looking around, and i found that
channels are screwed up. i mean, if you open the
scanned image with gimp, and separate the channels,
you can see the red one is OK, but blue and green
are not good. i mean, too many lights and shadows.
(i can show you another image if it's not clear with
this one)<br>
<br>
i have two of those scanners, and both of them do
the same thing. i have tried with several computers,
and got same results. however, with other scanners,
scanimage works fine. the same aplies for xsane. <br>
<br>
i don't mind getting my hands into the driver
(genesys_gl841), BUT, i don't know how to use
usbsnoopy under windows (i tried, but it did
nothing), and even if it worked, i wouldn't know
what to do with that data. <br>
<br>
also, i found this: <a moz-do-not-send="true"
href="http://old.nabble.com/Backend-for-plustek-Opticbook-3600-td26641970.html"
target="_blank">http://old.nabble.com/Backend-for-plustek-Opticbook-3600-td26641970.html</a><br>
but i understood very little if anything. <br>
<br>
so, i need to get this scanner working, driver is
doing weird things (under windows, scanners work as
expected), and i don't know what to do with it. <br>
<br>
PS: i tried to activate debugging, but scanimage
wouldn't accept a --debug option, and setting just
the debug vars did nothing (SANE_DEBUG=255 and so
on). i also tried to recompile the driver to
activate debug support (i'm working with packages
from debian wheezy's repos), but it told me this:<br>

Hello,<br>
<br>
if enabling debug traces with:<br>
<br>
export SANE_DEBUG_GENESYS=255<br>
export SANE_DEBUG_GENESYS_LOW=255<br>
export SANE_DEBUG_GENESYS_GL841=255<br>
<br>
before running a color preview with:<br>
scanimage -d genesys --clear-calibration --mode Color
2>preview.log >preview.pnm<br>
<br>
<br>
doesn't work, ie the preview.log file is empty, you may
consider recompiling SANE.<br>
When running the 'configure' command, be sure to 'cd' to the
top directory of the sources and run ./configure , so you
get sure the 'configure' run is the one from SANE, not
another one in the PATH.<br>
Although OpticBook 3600 support is in SANE 1.0.22, it
would be better to compile SANE 1.0.23. You don't have to
install the compiled version to test it. To test you may
preload the freshly compiled backend by doing:<br>
<br>
export LD_PRELOAD=.libs/libsane-genesys.so<br>
<br>
and run scanimage, xsane or whatever frontend from the
'backend' subdirectory.<br>
<br>
Regards,<br>
Stef<br>

Hello,<br>
<br>
the calibration message is harmless when scanimage is run with
--clear-calibration. There should be some *.pnm files created in the
working directory when debug is activated. May you send them to me ?
THey will give information on the calibration process.<br>
<br>
Regards,<br>
Stef<br>
