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.hen the black or color ink out light is flashing or on, you cannot clean the print head. Replace the appropriate ink cartridge first. Do not start clean or check the print head nozzles while printing is in progress; otherwise your printout may be marred.
