Balance Colors
There are three methods for balancing colors to prevent a primary color (cyan, magenta, or 
yellow) from overpowering the other colors:
PhaserMatch and PhaserCal Software: Provides the most accurate color balance 
adjustment by using instrument-based measurements. If using PhaserMatch/PhaserCal 
software, it is not necessary to perform either the Basic Color Balance or Advanced Color 
Balance procedures.
Basic Color Balance: Provides a color balance adjustment that is appropriate for most 
printing needs. Twelve basic, visual evaluations are made to adjust the darkness of three 
shades of each toner color independently. 
Advanced Color Balance: Provides a finer color balance adjustment than the Basic Color 
Balance procedure. Two or more advanced visual evaluations are made to ensure that 
equal mixtures of the primary colors produce a neutral gray. 
PhaserMatch and PhaserCal Software
PhaserMatch Color Management and PhaserCal Color Calibration software provide 
instrument-based color calibration tools. These applications use spectrophotometer or scanner 
measurements to achieve optimum calibration of your Phaser 7750 printer. 
PhaserCal software can be used with any Phaser 7750 Color Laser Printer and is supplied with 
Phaser 7750DN, 7750GX, and 7750DXF configurations. For more information on
