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.

See “Printing the Nozzle Check Pattern” on page 27.

If the print head nozzles are still not clean, turn off the printer and perform another Print Head Deep Cleaning after 24 hours.
