Routine Maintenance
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.

Print Head Deep Cleaning
If print quality does not improve by standard Print Head Cleaning, try Print Head Deep Cleaning,
which is a more powerful process. Note that cleaning the Print Head causes used ink to be absorbed
in the ink absorber. Print Head Deep Cleaning consumes more ink than standard Print Head
Cleaning, so perform this procedure only when necessary.
