3.17 White Level From Paper
This function uses white as the reference for the colors in the background of
documents when scanning.
Normally, when text written on paper in red, blue or some other color is scanned, the
texture of the paper is scanned, and the resulting images have a great deal of noise.
When the White Level From Paper function is used, the paper texture is skipped
over, and clear images are obtained.
IMPORTANT NOTES:
•
The White Level From Paper function detects the color at a position of 3 mm or so
along the top edge of the paper. It will not work properly if the colors in other areas
of the paper differ from the color at this position.
•
When White Level From Paper is used, the scanned image will become white for
the 3 mm or so (up to 10 mm depending on the scanning conditions) from the top
edge of the paper. However, if the reference plate and flatbed sheet are set to
black, this area will not become white.
•
White Level From Paper cannot be used at the same time as Automatic Crop,
Deskew, Margin or Automatic Threshold.
•
White Level From Paper cannot be used in the Color mode or MultiStream
(Binary&Gray or Binary&Color) mode.
