How to Perform Cleaning
When a printing test reveals dot drop-out or the like, perform cleaning for just the group of heads that is incapable of
correct printing. Compared with performing cleaning for all heads, this can reduce the amount of ink consumed.

Perform a printing test again to make sure the dot drop-out has been corrected.
If the problem persists, try performing cleaning a second time.
If the problem doesn't go away even after performing cleaning two or three times, then try cleaning using a
different method.
