Sensitivity
• Low : documents requiring only a small amount of color to be saved
as color/grayscale images. Used for capturing documents that are
primarily black text with small logos, or contain small amounts of
highlighted text or small colorful photos.
• Medium : documents requiring more color, as compared with the Low
option, before they are saved as color/grayscale images.
• High : documents requiring more color, as compared with the Medium
option, before they will be saved as color/grayscale images. Used for
distinguishing documents containing medium- to large-size colorful
photos from plain black text. Photos with neutral colors may require
adjustments to the
Color Threshold or Color Amount values in order
to be captured correctly.
• Custom : allows you to manually adjust the Color amount and/or
Color threshold.
NOTE: When setting Sensitivity values, it is suggested that you start
with the Medium option and scan a typical job set. If too
many documents were returned as color/grayscale vs. black
and white, then change to the
High option and re-run the job.
If too few documents were returned as color/grayscale vs.
black and white, then change to the
Low option and re-run
the job. If none of these options provide the desired result,
select
Custom to manually adjust Color Amount and/or Color
Threshold. Custom also allows access to the Learn mode
which provides a method for the scanner to analyze
documents and recommend settings.
Color amount — the amount of color that needs to be present in a
document before it will be saved as either color/grayscale. As the value
of
Color Amount increases, more color pixels are required. Valid values
are 1 to 200 .
Color threshold — the color threshold or saturation (i.e., pale blue vs.
dark blue) at which a given color will be included in the color amount
calculation. A higher value indicates that a more intense color is
required. Valid values are
0 to 100 .
Learn — allows you to calculate your settings based on representative
color documents scanned. Before selecting Learn , place at least 5
representative color documents in the input elevator. The documents
will be scanned and analyzed to determine the recommended
Color
amount .
NOTE: These Color amount and Color threshold sliders will be updated
automatically. If these values do not provide the desired results
with your job set, you may need to manually adjust the
Color
Threshold .
