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.
