The printed page appears tinted. Can I slightly adjust the color?
Sometimes a user 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 be used to create 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 under the Color Balance menu will slightly increase (or decrease)
the amount of toner used for the chosen color. For example, if a user believes the overall printed page to be too red,
then decreasing both magenta and yellow could potentially improve color preferences.
For information about adjusting the Color Balance setting, see the Menus and Messages Guide on the Software and
Documentation CD.
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. For more information, see the
Menus and Messages Guide on the Software and Documentation CD.
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, a user may want to apply a different 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.
Users may select any of the different color conversion tables for RGB or CMYK:
Color conversion table
RGB
CMYK
Note: The Manual Color Correction setting is not useful if the software program does not specify colors with RGB or
CMYK combinations. It is also not effective in situations where the software program or the computer operating system
controls the adjustment of colors.
How can I match a particular color (such as a corporate logo)?
Occasionally, users have a need for the printed color of a particular object to closely match a specific color. For example,
a user may need to match the color of a corporate logo. While instances can occur in which the printer cannot exactly
reproduce the desired color, users should be able to identify adequate color matches for the majority of cases.
The Color Samples menu item can provide useful information in helping solve this particular type of color-matching
problem. The nine Color Samples values correspond to color conversion tables in the printer. Selecting any of the Color
Samples values 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.
