3-2 When Head Cleaning Is Not Effective
Performing More Powerful Cleaning
When the problems such as dot drop-out are not cleared up by the "normal cleaning," try the more forceful "medium
cleaning" or the even more forceful "powerful cleaning." Note, however, that this consumes more ink than "normal
cleaning," and too-frequent use may damage the print heads themselves. Avoid using it more than necessary.
