Should I use PostScript or PCL emulation printer software?
What settings should I use for the best color?
The PostScript driver is strongly recommended for best color
quality. The default settings in the PostScript driver provide the
preferred color quality for the majority of printouts.
Why doesn't the printed color match the color I see on the
computer screen?
The color conversion tables used in Auto Color Correction mode
generally approximate the colors of a standard computer
monitor. However, because of technology differences that exist
between printers and monitors, there are many colors that can
also be affected by monitor variations and lighting conditions.
For recommendations on how the printer color sample pages
may be useful in solving certain color-matching problems, see
the question, "How can I match a particular color (such as a
corporate logo)?"
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
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.
Selecting which Color Samples set 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 program (RGB or CMYK
combinations). When the printer Color Correction setting is set
to Off, the color is based on the print job information; and no
color conversion is implemented.
Note: The Color Samples pages are not useful if the software
program does not specify colors with RGB or CMYK
combinations. Additionally, certain situations exist in which the
software program or the computer operating system adjusts
the RGB or CMYK combinations specified in the program
through color management. The resulting printed color may
not be an exact match of the Color Samples pages.
