Paper. Your print cartridges are not compatible with this type of paper.
• Use a paper that is a heavier weight or bright white.

1 Align the print cartridges. For more information, see “Aligning print cartridges” on page 81. If print quality has
not improved, continue to the next step.
2 Clean the print cartridge nozzles. For more information, see “Cleaning the print cartridge nozzles” on
