What Is Manual Color Correction - Lexmark CX310n Service Manual

The printed page appears tinted. Can I adjust the color?
Sometimes a printed page may appear tinted (for example, everything printed seems to be too red). This can be caused
by environmental conditions, paper type, lighting conditions, or user preference. In these instances, adjust the Color
Balance setting to create a more preferable color. Color Balance provides the user with the ability to make subtle
adjustments to the amount of toner being used in each color plane. Selecting positive or negative values for cyan,
magenta, yellow, and black (from the Color Balance menu) will slightly increase or decrease the amount of toner used
for the chosen color. For example, if a printed page has a red tint, then decreasing both magenta and yellow could
potentially improve the color balance.
My color transparencies seem dark when they are projected. Is there anything I can do to
improve the color?
This problem most commonly occurs when projecting transparencies with reflective overhead projectors. To obtain
the highest projected color quality, transmissive overhead projectors are recommended. If a reflective projector must
be used, then adjusting the Toner Darkness setting to 1, 2, or 3 will lighten the transparency. Make sure to print on the
recommended type of color transparencies.

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.
•
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
Press Menu to open the Admin menus.
2
Select Settings, and press Select.
3
Select Quality, and press Select.
4
Select Color Correction, and press Select.
5
Select Manual, and press Select.
The printer is in manual mode, and you need to select a color conversion table.
6
Press Back to return to the Quality menu, select Manual Color, and press Select.
7
Select the appropriate color conversion table for the affected object type.
