Check the ink level, and install a new print cartridge if necessary.

See “Improving print quality” on page 61.

To avoid ink smudging when you are working with the following media, remove each sheet as it exits, and allow it
to dry:

Document with graphics or images

Photo paper

Heavy weight matte or glossy paper

Transparency

Labels

Envelopes

Iron-on transfer

Note: Transparencies may take up to 15 minutes to dry.

Use a different brand of paper. Each paper brand accepts ink differently and prints with color variations. Use Lexmark
Premium Photo Paper if you are printing photos or other high-quality images.

Use only new, unwrinkled paper.
