Print troubleshooting
Improving print quality
If you are not satisfied with the print quality of a document, make sure you:
• Use the appropriate paper for the document. Use Lexmark Premium Photo Paper if you are printing photos or
other high-quality images.
Note: To prevent smudging or scratching, avoid touching the printed surface with your fingers or sharp objects.
For best results, remove each printed sheet individually from the paper exit tray, and allow the prints to dry at
least 24 hours before stacking, displaying, or storing.
• Use a paper that is a heavier weight, bright white, or coated.
• Select a higher print quality.
If the document still does not have the print quality you want, follow these steps:
1 Align the print cartridges. For more information, see “Aligning the print cartridges” on page 25.
If print quality has not improved, continue to step 2.
2 Clean the print cartridge nozzles. For more information, see “Cleaning the print cartridge nozzles” on page 25.
If print quality has not improved, continue to step 3.
3 Remove and reinsert the print cartridges. For more information, see “Removing a used print cartridge” on
page 23 and “Installing print cartridges” on page 24.
If print quality has not improved, continue to step 4.
4 Wipe the print nozzles and contacts. For more information, see “Wiping the print cartridge nozzles and contacts”
on page 26.
If print quality is still not satisfactory, replace the print cartridges. For more information, see “Ordering supplies”
on page 27.
