Calibrating the Scanner
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 that 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 down into the page feed slot of the
scanner. Align the calibration sheet to the calibration alignment mark on 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 Letter size (8.5” x 11.69”) instead; however, the calibration effect
may be less good than the special calibration sheet.
2. Click Start > All Programs > Your scanner model name > Calibration
Wizard . (For Windows 8.1 users: Point your mouse cursor to the upper or
lower right corner of your screen to open the Charm bar. Click on the Start
charm, then click on the downwards arrow button in the lower left corner of
the screen. The
Apps screen will be shown. Move your cursor to the right edge
of the screen to scroll right until you find Your scanner model name , and
then click on Calibration Wizard .)
3. Click Next from the Calibration Wizard that pops up and then click Calibrate
Now... .
4. Click on the Start button to begin the calibration process.
5. The scanner pulls the calibration sheet through the scanner, which completes
this scanner calibration. After the calibration is complete, click OK and then
click Finish .
