Solution 7: Clean the ink cartridges
Clean the ink cartridges if you see the following in the diagnostic report:
Color bars: Color bars are ragged or irregularly streaked or faded; have regular,
white streaks; or are not a uniform color throughout the bar, clean the ink cartridges.
Large-font text: Letters are smeared or ragged on one end.

NOTE: Do not clean ink cartridges unnecessarily. Unnecessary cleaning wastes ink
and shortens the life of the ink nozzles.
If the issue persists, continue to the next step.
