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 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. You can select any of the different color conversion tables for RGB or CMYK: Color conversion table RGB CMYK Settings • sRGB Display • Display-True Black • sRGB Vivid • Vivid • Off • US CMYK • Euro CMYK • Vivid CMYK • Off Note: The Manual Color Correction setting is not useful if the software application does not specify colors with RGB or CMYK combinations. It is also not effective in situations where the software application or the computer operating system controls the adjustment of colors. How can I match a particular color (such as a corporate logo)? Occasionally, you may have a need for the printed color of a particular object to closely match a specific color. For example, you may need to match the color of a corporate logo. While instances can occur in which the printer cannot exactly reproduce the desired color, you 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. You can examine the color samples pages and 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 application. For instructions, see the software application Help. Manual Color Correction may be necessary to utilize the selected color conversion table for the particular object. Troubleshooting 238
