target. The process will take about eight minutes.

CCD Calibration

To make sure all of the pixels in the CCD react equally to low levels of
light, your scannerÕs CCD should be calibrated. If it is not, you may see
some faint single-pixel striping in very dark areas of positives or in
light areas of images that were scanned from negatives. The problem,
which is present in all CCD scanners, is most noticeable when you scan
35 mm negatives.
The CCD calibration information is stored in a ßash PROM inside the
scanner, not on your hard disk. This means that the CCD calibration is
preserved when you move the scanner to a new computer.
Support for CCD calibration was added in ColorFlex 1.9. If your scan-
ner came with version 1.9 or higher, then CCD calibration has been
done at the factory; we highly recommend that you do not repeat it
again yourself (recalibration is neither necessary or advisable). How-
ever, if you are upgrading your software for use with a scanner that
was delivered with an older version of ColorFlex, then you might want
to calibrate the CCD yourself if you are having trouble with striping as
described above.
Use the procedure below to calibrate your CCD sensor using ColorFlex.
