Medium Cleaning Method
The print heads are important components that discharge ink. They require periodic and appropriate mainte-
nance. When problems such as dot drop-out are not resolved by normal cleaning (
"Printing Tests and Normal Cleaning(P.
132)"
), perform the more forceful "medium cleaning" to remove clogging from the print heads.
IMPORTANT
Medium cleaning consumes more ink than normal cleaning, and overly frequent use may damage the print heads themselves.
Avoid performing this operation more than necessary.
