Color is patchy or distorted at the edges of the image. If the document is very thick or warped at the edges, the edges of the image may be discolored. Cover the edges of the document with opaque paper to block outside light. If part of the document extends beyond the document table, that edge may not be in contact with the document table. Change the position of the document. The image is faint or out of focus. Check that the document is placed flat against the document table. Darken your image with the brightness setting in your software. The image is too dark. Adjust the brightness with your software. Also check the brightness and contrast of your display screen. Straight lines are jagged in the image. The document may be placed at an angle on the document table. Position it so that the horizontal and vertical lines are carefully aligned with the scales on the top and side of the document table. The image does not look the same as the original. Try different combinations of image settings using your scanner software. 4-6 Troubleshooting
