cartridges may be installed 
incorrectly, may be low, or may 
be defective.

Check the printer control panel for a

distributed evenly on each cartridge 
roller, then reinstall the toner cartridges. 
Replace a cartridge if necessary.

the Quality tab of the printer 
driver are incorrect.

Verify the Color Matching settings in the 
printer driver. Change as necessary.

The printer needs a color 
calibration.

Calibrate the printer. See
