Troubleshooting 187 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.

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.

—Produces brighter, more saturated colors and may be
applied to all incoming color formats.

—Produces an output that approximates the

Note:
Black toner usage is optimized for printing photographs.

True Black
—Produces an output that approximates the

toner to create all levels of neutral gray.
sRGB Vivid
—Provides an increased color saturation for the
sRGB Display color correction.
Note:
Black toner usage is optimized for printing business
graphics.

US CMYK
—Applies color correction to approximate the SWOP

Euro CMYK
—Applies color correction to approximate Euroscale
color output.

—Increases the color saturation of the US CMYK
color correction setting.

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.
