• Custom: makes the Color Amount and/or Color Threshold options
available.
NOTE: When setting Auto Color Detect 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 option to manually adjust Color
Amount and/or Color Threshold.
Color Amount: the amount of color that needs to be present in a
document before it will be saved as either color or 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 intensity (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 — if Low, Medium and High options do not give you the desired
results, use the Learn option.
1. Click Learn and follow the prompts.
2. Place at least 5 representative color documents in the input tray and
click OK. These documents will be analyzed and the recommended
color amount will be calculated for you.
3. Write down the Color Amount and Color Threshold values that
are displayed in the dialog box as these are the settings you will be
required to use in your application.
NOTE: These settings were calculated based on the representative
color documents scanned. If these values do not provide the
desired results with your production job set, you may need to
manually adjust the Color Threshold.
