(14) If any abnormal data is observed, specify the problem areas as follows:
Select Specified Part in Calibration.
(15) The mouse arrow cursor changes to a cross cursor when moved over the data. Click
the left mouse button with the mouse positioned over the streak data. The selected
area is shown in blue. Repeat this procedure for any additional streaks.
Areas that have been selected (shown in blue) can be deselected by clicking the left
mouse button again. To deselect all selected areas, click the Clear button.
(16) Once all required areas have been specified, remove the calibration sheet and clean
the glass and table surfaces. Check the calibration sheet for dust and dirt, then click
the [Execute] button.
(17) Return to step (10) and verify the calibration results.
If you perform the calibration procedure several times with no discernible results, there
may be a problem with the scanner itself. In this case, please contact your Graphtec
vendor.
Color Correction
Perform color correction if there is any discrepancy in color in parts of the scanned image
even after you have calibrated the scanner.
Handle the color correction sheet with care so that it is does not get soiled, bent or
scratched. A soiled, bent, or scratched sheet will not give good results. The color correction
sheet is a consumable item, and replacement sheets can be purchased from your
sales representative or nearest Graphtec vendor.
