Glass Dirt Alert Does Not Disappear

If the glass dirt alert screen appears after cleaning the inside of the scanner, check the glass surface again. If there
are scratches on the glass, they will be detected as a glass dirt.
Glass part will be required to replace. Contact your local dealer to repair.

Colors Are Uneven in the Scanned Image

If the scanner is subject to strong light such as direct sunlight, the sensor inside the scanner misdetects the light
and colors in the scanned image become uneven.
❏ Change the orientation of the scanner so that no strong light is falling on the front of the scanner.
❏ Move the scanner to a location where it will not be subjected to strong light.
