Print Head Deep Cleaning
If print quality does not improve by standard print head cleaning, try deep cleaning, which is
a more powerful process. Perform print head deep cleaning from the printer driver.
Note
Print head deep cleaning consumes more ink than standard print head
cleaning, so perform this procedure only when necessary.
