Print Head Cleaning

Clean the Print Head if lines are missing or if white streaks appear in the printed nozzle check
pattern. Cleaning unclogs the nozzles and restores the print head condition. Note that cleaning the
Print Head causes used ink to be absorbed in the ink absorber. Cleaning the Print Head consumes
ink, so perform Print Head Cleaning only when necessary.
