If defects are seen on the Print Quality Diagnostic report, follow the steps below:
1.
If the Print Quality Diagnostic report shows faded, partial, streaked, or
missing color bars or patterns, check for depleted ink cartridges, and
replace the ink cartridge that corresponds to the defective color bar or color
pattern. If there is no depleted ink cartridge, remove and reinstall all ink
cartridges to make sure they are properly installed.
2. Align the printhead. For more information, see Align the printhead.
3. Clean the printhead. For more information, see Clean the printhead.
4. Replace the printhead. For more information, see Remove and reinstall the

Cause: Print quality problems can have many causes: software settings, a poor
image file, or the printing system itself. If you are unhappy with the quality of your
prints, a Print Quality Diagnostic page can help you determine if the printing
