If dots or streaks appear in one or more groups, clean the printhead. If this does not solve the problem, contact HP.

If streaks appear in multiple color bands, see if the problem still persists by performing an additional print head cleaning, and then contact HP. A component other than the ink cartridge is probably causing the problem.
