<BR>
|
|
<EM>> But I can't get rid of this funky veritcal line on all my scans.
|
|
</EM><BR>
|
|
<P>This looks like broken illumination correction. I don't know about
|
|
<BR>
|
|
this scanner in particular so I'm guessing, but...
|
|
<BR>
|
|
<P>If this scanner has a self-calibration step, it probably uses a white
|
|
<BR>
|
|
reference that might have been damaged. If the profile is calibrated
|
|
<BR>
|
|
at the factory, the sensor might have slipped, causing the profile
|
|
<BR>
|
|
to not match the device.
|
|
<BR>
|
|
<P>How 'bout the light? It looks like the artifact is outside the focal
|
|
<BR>
|
|
plane, so maybe the lamp itself is damaged?
|
|
<BR>
|
|
<P>Whatever it is, it moves with the sensor/lamp so it is not the bed.
|
|
<BR>
|
|
<P>A spot on the sensor?
|
|
<BR>
