Powerful Cleaning Method

The print heads are important components that discharge ink. They require periodic and appropriate maintenance. When problems such as dot drop-out are not resolved by Medium Cleaning, perform the more forceful Powerful Cleaning to remove clogging from the print heads.
IMPORTANT

Powerful Cleaning is more forceful cleaning that consumes more ink than Medium Cleaning.
