Powerful Cleaning Method
The print heads are important components that discharge ink. They require periodic and appropriate main-
tenance. 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.
Powerful cleaning consumes more ink than medium cleaning, and overly frequent use may damage the print heads
themselves. Avoid performing this operation more than necessary.
