CHECK THE DARKNESS, BRIGHTNESS, AND CONTRAST SETTINGS

The Toner Darkness setting may be too light, the Brightness setting may be too light, or the Contrast setting may be too low.

•For Macintosh users:

1Choose File > Print.

2From the print options pop-up menu, choose Printer Features.

3Choose a higher value for the Toner Darkness, Brightness, and Contrast settings.

LOAD PAPER FROM A FRESH PACKAGE

The paper may have absorbed moisture from high humidity. Store paper in its original wrapper until you use it.

AVOID TEXTURED PAPER WITH ROUGH FINISHES

CHECK THE PAPER TYPE SETTING

Make sure the Paper Type setting matches the paper loaded in the tray or feeder:

•From the printer control panel Paper menu, check the Paper Type setting.

•For Windows users, check this setting from Print Properties.

•For Macintosh users, check this setting from the Print dialog.

MAKE SURE THE PRINT OR TONER CARTRIDGE IS NOT LOW ON TONER

Warning—Potential Damage: Be careful not to touch the photoconductor drum. Doing so may affect the print quality of future print jobs.

2Firmly shake the cartridge side-to-side and front-to-back several times to redistribute the toner.

3Reinsert the cartridge.

Note: If print quality does not improve, then replace the cartridge of the color that is not printing.
