Notes:
•
Manual color correction is not useful if the software program does not specify colors with RGB or CMYK combinations.
It is also not effective in situations in which the software program or the computer operating system controls the
adjustment of colors.
•
The color conversion tables—applied to each object when Color Correction is set to Auto—generate preferred colors
for the majority of documents.
To manually apply a different color conversion table:
1
From the Quality menu, select Color Correction, and then select Manual.
2
From the Quality menu, select Manual Color, and then select the appropriate color conversion table for the affected object
type.

How can I match a particular color (such as a corporate logo)?
From the printer Quality menu, nine types of Color Samples sets are available. These are also available from the Color Samples
page of the Embedded Web Server. Selecting any sample set generates a multiple‑page printout consisting of hundreds of
colored boxes. Either a CMYK or RGB combination is located on each box, depending on the table selected. The observed color
of each box is obtained by passing the CMYK or RGB combination labeled on the box through the selected color conversion
table.
By examining Color Samples sets, a user can identify the box whose color is the closest to the desired color. The color
combination labeled on the box can then be used for modifying the color of the object in a software program. For more
information, see the software program Help topics. Manual color correction may be necessary to utilize the selected color
conversion table for the particular object.
