Which Color Samples pages to use for a particular color-matching problem depends on the Color Correction setting being
used (Auto, Off, or Manual), the type of object being printed (text, graphics, or images), and how the color of the object is
specified in the software application (RGB or CMYK combinations). When the printer Color Correction setting is set to

Color Samples pages to use.
Note: The Color Samples pages are not useful if the software application does not specify colors with RGB
or CMYK combinations. Additionally, certain situations exist where the software application or the
computer operating system adjusts the RGB or CMYK combinations specified in the application
through color management. The resulting printed color may not be an exact match of the Color
Samples pages.

What are Detailed Color Samples and how do I access them?
This information applies to network models only.
Detailed Color Samples are pages similar to the default pages of color samples accessible from the Quality Menu on the
printer operator panel or from the Configuration Menu in the printer Embedded Web Server. The default color samples
accessed by these methods have an increment value of 10 percent for Red (R), Green (G), and Blue (B) values.
Collectively, these values are known as RGB color. If the user finds a value on the pages that is close, but would like to scan
more colors in a nearby area, the user can use the Detailed Color Samples to input the desired color value and a more
specific or lower increment value. This lets the user print multiple pages of colored boxes that surround a specific color of
interest.
