Routine Maintenance
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.

Load a sheet of A4 or Letter-sized plain paper in the Auto Sheet Feeder or the
Front Feeder.
