Using the White Calibration Sheet
• Do not leave the white calibration sheet in locations that are exposed to
direct sunlight or that are subject to high temperatures or humidity.
• Do not bend or wrinkle the white calibration sheet.
• When cleaning the white calibration sheet, use a soft cloth that is dipped
in a weak, neutral detergent solution, and then wipe its wet surface off
with a dry, soft cloth.
White level calibration is required in the following circumstances.
• When you use the scanner cartridge for the first time after purchase
• When the system needs to update the white level calibration data.
The white level calibration data is stored into memory and used for main-
taining the correct colour balance of scanned images. When a message
appears and prompts you to load the white calibration sheet, click the OK
button and perform white level calibration.
