Calibrating the Scanner
The scanner requires two types of calibration:
•
Focus calibration
adjusts the positioning of the scanner's 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
scanner's 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 scanner's CCD. The white calibration is stored in the scanner's
flash PROM, so it is preserved when 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.
