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 b est color quality. The default settings in the PostScript dri ver
provide the preferred color quality for the majority o f 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 g enerally approximate the colors of a standard
computer monitor. However, because of technology dif ferences that exist between printers and monit ors, there are
many colors that can also be affected by monitor variations a nd 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, everyt hing printed seems to be too red). This can be
caused by environmental conditions, paper type, lighting condition s, 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 inc rease 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 pr ojected. Is there anything I can do to improve th e color?
This problem most commonly occurs when projecting transparencies with reflective overhead projectors. To obtain
the highest projected color quality, transmissive overhea d projectors are recommended. If a reflective projector
must be used, then adjusting the Toner Darkness setting to 1, 2, or 3 will lighten the trans parency. 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 o f object being printed (text, graphics, or image s), 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:
1From the Quality menu, select Color Correction, and then select Manual.
2From the Quality menu, select Manual Color, and then select the appropriate color conversion table fo r the
affected object type.
