Troubleshooting
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, Color
Balance 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 decreases to both magenta
and yellow could potentially improve color preference.
Is it possible to increase the gloss in the printed output?
Obtain additional gloss by printing using the 1200 dpi Print Resolution Setting.
My color transparencies seem dark when 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 Toner Darkness settings to 1, 2, or 3 will lighten the transparency. Be sure to print on the recommended
type of color transparencies. For more information, see “Understanding paper and specialty media guidelines” in the User’s
Guide on the Software and Documentation CD.
Color Saver must be Off to adjust Toner Darkness.
What is Manual Color Correction?
The color conversion tables applied to each object on the printed page 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 the RGB and CMYK color conversion table mappings as defined in the Manual Color
menu. Users may select any of five different color conversion tables available for RGB objects (sRGB Display, Display—
True Black, sRGB Vivid, Off, and Vivid) and any of four different color conversion tables available for CMYK objects
(US CMYK, Euro CMYK, Vivid CMYK, and Off).
Note: The Manual Color Correction setting is not useful if the software application does not specify colors
with RGB or CMYK combinations, or in certain situations where the software application or the
computer operating system adjusts the colors specified in the application through color management.
How can I match a particular color (such as a color in a corporate logo)?
Occasionally, users have a need for the printed color of a particular object to closely match a specific color. A typical
example of this is when a user is trying 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 to 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.
The user can examine the color samples pages and identify the box whose color is the closest to the desired color. If the
user finds a box whose color is close to the desired color match, but the user would like to scan the colors in that area in
more detail, then the user can access the Detailed Color Samples by using the printer Embedded Web Server interface,
which is only available on network models.
