<div dir="ltr">Hi all.
<div><br>
</div>
<div>I just received a Canoscan LiDE 210 and just try to get it
working properly.</div>
<div><br>
</div>
<div>Just noticed that when using it in Linux, the results of
any kind of scan shows a couple of small green bands on the
left side, vertical and about 1 cm width.</div>
<div><br>
</div>
<div>The strange thing is that those bands are Not shown when
scanning from Micrososft Windows with the Canon suplied
driver.</div>
<div>There image there is perfect. It seems to only affect Sane.</div>
<div>
<br>
</div>
<div>I've tried both on Debian unstable and on Ubuntu 14.04 but
same results.</div>
<div><br>
</div>
<div>Also tried re-calibrating the scanner from Windows several
times, but same issue.<br>
</div>
<div>Removing the calibration file and again.</div>
<div><br>
</div>
<div>Also from different front-ends (xsane and skanlite) same
results.</div>
<div><br>
</div>
<div>The fact that only affects Linux makes me wonder if is some
kind of software issue or is a faulty hardware.</div>
<div>I am in time to return it but just wanna know first if i am
doing something wrong, or is a software issue.</div>
<div><br>
</div>
<div>Have some samples to check the issue if desired.</div>
<div><br>
</div>
<div>Thanks in advance for the help and also for the great job
you all do to get scanners working.</div>

Hello,<br>
<br>
maybe an upload error, I'm not seeing any green band on the
linux scan.<br>
However, you can send an another one directly to me, with debug
traces log generated by running scanimage with debug by executing
these commands:<br>
xport SANE_DEBUG_GENESYS=255<br>
export SANE_DEBUG_GENESYS_LOW=255<br>
export SANE_DEBUG_GENESYS_GL646=255<br>
export SANE_DEBUG_GENESYS_GL841=255<br>
export SANE_DEBUG_GENESYS_GL843=255<br>
export SANE_DEBUG_GENESYS_GL847=255<br>
export SANE_DEBUG_GENESYS_GL124=255<br>
scanimage -d genesys --clear-calibration --resolution 300 --mode
Color 2>debug.log >scan.pnm<br>
<br>
Maybe the internal geometry of your scanner model is slightly
different, and calibration happens on an unexpected black area.<br>
<br>
