Calibrating the Scanner

Calibrating the Scanner
The scanner requires two types of calibration:
•
Focus calibration adjusts the positioning of the scanners optics for
each zoom level. If your scans are coming out unfocused or at slightly
the wrong size, then you may need to make a new focus calibration to
adjust the zoom mechanism. The focus calibration is stored in the
scanners flash PROM, so it is preserved when you move the scanner to
a new computer. See "Focus Calibration" on page 21 for more
information.
•
White calibration is only required for reflective scans (it is done
automatically for transparencies). During calibration, the scanner
scans a white target to establish the white point along the full length
of the scanners CCD. The results of the white calibration scan are
saved on your computers hard disk, so you must make a new white
calibration if you move the scanner to a new computer. See "White
Calibration for Reflectives" on page 22 for more information.
Both of the calibration procedures are simple and are initiated from the
FlexColor program.
