When Normal Cleaning Is Not Effective

Medium Cleaning Method

The print heads are important components that discharge ink. They require periodic and appropriate main-
tenance. When problems such as dot drop-out are not resolved by normal cleaning, 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 them-
selves. Avoid performing this operation more than necessary.
