What is manual color correction?
When manual color correction is enabled, the printer employs user
‑
selected color conversion tables to
process objects. However, Color Correction must be set to Manual, or no user
‑
defined color conversion will
be implemented. Manual color correction settings are specific to the type of object being printed (text,
graphics, or images), and how the color of the object is specified in the software program (RGB or CMYK
combinations).
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.
•
When Auto Color Correction is selected, the color conversion tables will generate preferred colors
used for the majority of the documents.
To manually apply a different color conversion table, do the following:
1
From the Quality menu on the printer control panel, select Color Correction , and then select Manual .
2
From the Quality menu on the printer control panel, 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)?
Nine types of Color Samples sets are available from the Quality menu on the printer control panel. 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.
