Operation Manual

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 preferred color quality for the majority of printouts.
Why doesn't the printed color match the color that 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 dierences that exist between printers and
monitors, there are many colors that can also be aected 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 color in a corporate logo)?”
The printed page appears tinted. Can I slightly adjust the color?
Sometimes you may consider printed pages to 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, adjusting the Color Balance setting may create more preferable color. Color Balance lets
you 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 under the Color Balance menu will slightly increase (or
decrease) the amount of toner used for the chosen color. For example, if you believe the overall printed page
to be too red, then decreasing both magenta and yellow could potentially improve color.
My color transparencies seem dark when being 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. For more information about the paper
and media specifications, see the User's Guide on the Software and Documentation CD.
What is manual color correction?
The color conversion tables applied to each object when using the default Auto Color Correction setting
generate preferred color for the majority of documents. Occasionally, you may want to apply a dierent color
table mapping. This customization is accomplished using the Manual Color menu and the Manual Color
Correction setting.
Manual Color Correction applies to RGB and CMYK color conversion table mappings as defined in the Manual
Color menu.
You can select any of the dierent color conversion tables for RGB or CMYK:
