Try one or more of the following:

CHECK THE PAPER TYPE AND WEIGHT SETTINGS

Make sure the paper type and weight settings match the paper loaded in the tray or feeder:

1From the printer control panel Paper menu, check the Paper Type and Paper Weight settings.

2Before sending the print job, specify the correct paper type setting:

•For Windows users, specify the paper type from Print Properties.

•For Macintosh users, specify the paper type from the Print dialog.

MAKE SURE THE PRINT CARTRIDGE IS NOT LOW ON TONER

When 88.xx [color] cartridge low appears, make sure that toner is distributed evenly among all four print cartridges or whichever color has the shadow images.

1Remove the print cartridge.

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 print cartridge.

Note: If print quality does not improve, replace the print cartridge of the color that is giving a shadow.

If the problem continues, the printer may need to be serviced. For more information, contact customer support.
