Medium and Powerful Cleaning
When normal cleaning ("Printing Test and
Normal Cleaning" (First Step Guide)) does
not correct dot drop-out, perform the more
powerful cleaning, a "medium cleaning, "
two or three times. If the condition is not
improved, try the even more powerful
"powerful cleaning. "
NOTE
Ink consumption becomes larger in the
order of normal cleaning, medium cleaning,
and powerful cleaning.
Because the print heads are prone to
damage if cleaned too frequently, do not
perform cleaning more than necessary.
