5-2 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.
In the same way as for normal cleaning, choose and clean only the group of a head that are incapable of correct
printing.

Choose "medium cleaning" or "powerful cleaning."
