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

When 88.xx [color] cartridge low appears, make sure that toner is distributed evenly among all four cartridges:

1Remove the 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 cartridge.

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

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

Characters have jagged or uneven edges

If you are using downloaded fonts, verify that the fonts are supported by the printer, the host computer, and the software program.

Clipped images

Try one or more of the following:

CHECK THE GUIDES

Move the width and length guides in the tray to the correct positions for the paper size loaded.

CHECK THE PAPER SIZE SETTING

Make sure the paper size setting matches the paper loaded in the tray:

1From the printer control panel Paper menu, check the Paper Size setting.

2Before sending the job to print, specify the correct size setting:

•For Windows users, specify the size from Print Properties.

•For Macintosh users, specify the size from the Page Setup dialog.

Fine horizontal lines appear on color pages

You may notice fine, horizontal lines in photographs or pages with a high concentration of color. This can occur when the printer is in Quiet Mode. To fix this, set Quiet Mode to Off (Image/Photo).
