For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water.

Print head cleaning uses both color and black ink. To avoid wasting ink, clean the print head only if print quality declines (for example, if the printout is blurry or the color is incorrect or missing).
