Calibrating the Scanner
Attention
Please uninstall the extended paper width
sliders before you start the calibration.
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.
Follow the steps below to calibrate the scanner:
1.
Locate the Calibration Sheet, marked with an arrow on either edge at
both sides. It is used specifically for ADF Scanning calibration.
2. Insert the special calibration sheet into the ADF of the scanner, with an
arrow toward the scanner buttons.
Attention
Please insert the special calibration sheet
included with the scanner. Alternatively you
may also use any plain white sheet of paper
sized in A4 (216 x 297 mm) instead; however,
the calibration effect may be less beneficial
than with the special calibration sheet.
3. Click Start > All Programs > Your scanner model name > Calibration
Wizard.
