Calibrate the scanner if colors appear in areas that should be white, or colors of
the scanned image and the original vary a lot. This allows you to adjust and
compensate for variations which can occur in the optical component over time by its
nature.
The following describes how to calibrate the scanner:
1. Insert the special calibration sheet face up into the page feed slot of the
scanner.
Attention
Please insert the special calibration sheet included with the
scanner. Alternatively you may also use any plain white sheet
of paper sized in A6 (105 by 148 mm) instead; however, the
calibration effect may be less good than the special calibration
sheet.
2. Click on the Smart Touch icon
located on the Windows system tray.
3. Click [Calibrate] from the menu that pops up.
4. The scanner pulls the calibration sheet through the scanner, which completes
this scanner calibration.
