Print-Quality Problems
Phaser® 7750 Color Laser Printer
4-26
Color Settings
The print-quality mode and TekColor
correction directly control the quality of your prints. You
can change these settings in the printer driver or at the printer’s front panel.
Note
Driver settings override the printer’s front panel settings.
For more information on using color, go to Reference/Printing/Using Color on the User
Documentation CD-ROM.
Color Calibration
Color calibration procedures adjust the printer for optimal color output. Color settings may
need adjustment upon initial printer setup or when toner cartridges and imaging units are
replaced. There are two procedures: Lighten/Darken Colors and Balance Colors. If the overall
image appears either too light or dark, use the Lighten/Darken Colors procedure. If a finer
adjustment of the primary colors (cyan, magenta, and yellow) is needed, continue with the
Balance Colors procedure.
Lighten/Darken Colors
The Lighten/Darken Colors procedure increases or decreases all primary colors (cyan,
magenta, yellow, and black) to produce a lighter or darker image.
Caution
The Lightness Level affects all prints for all users. Changing this setting is generally not
recommended.
All Colors Too Light or Too Dark
Colors appear faded or too dark.
Calibrate the printer’s colors. Calibrating adjusts
the printer’s color balance and lightness level.
1. At the printer’s front panel, select Printer
Setup, select Calibration Setup, select
Calibrate Colors, then select Tutorial Page.
2. Follow the instructions on the Tutorial Page to
balance colors or lighten/darken colors.
