White Level From Paper When White Level From Paper is on, the first 3 mm of each document is analyzed and the background brightness level is adjusted so the background of the scanned document becomes white. White Level From Paper is "Off" when Dither or Grayscale is enabled. • Auto-when Dither and Binary are set to "None," white level is set from a preset white color definition. • On-white level is set from the first 3 mm of a scanned document. • Off-white level is set according to the white level calibration strip in the scanner (not the scanned document). Original Auto On Off If you scan colored paper (such as red or blue), the scanned paper's background color may cause the noise level to increase. NOTE: The document color 3 mm from the upper edge is detected. If a document contains colors that are different from the 3 mm sampled section color, this function may not work correctly.

White Level
From Paper
When
White Level From Paper
is on, the first 3 mm of each
document is analyzed and the background brightness level is adjusted
so the background of the scanned document becomes white.
White
Level From Paper
is “Off” when
Dither
or
Grayscale
is enabled.
•
Auto—when
Dither
and
Binary
are set to “None,” white level is set
from a preset white color definition.
•
On—white level is set from the first 3 mm of a scanned document.
•
Off—white level is set according to the white level calibration strip
in the scanner (not the scanned document).

If you scan colored paper (such as red or blue), the scanned paper’s
background color may cause the noise level to increase.
NOTE:
The document color 3 mm from the upper edge is detected. If
a document contains colors that are different from the 3 mm
sampled section color, this function may not work correctly.
