When Normal Cleaning Is Not Effective

Medium/Powerful Cleaning

I m p o r t an t
"Medium" and "powerful" cleaning consume more ink than "normal cleaning," and overly frequent
use may damage the print heads themselves. Avoid using it more than necessary.
When problems such as dot drop-out are not resolved by normal cleaning (P. 54 "Step 5 : Printing Tests and
Normal Cleaning"), perform the more forceful "medium cleaning" to remove clogging from the print heads. If
this still does not resolve the problem, try the even more forceful "powerful cleaning."
