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.
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.

corrected.
• If the problem persists, try performing medium cleaning again.
• If problems such as dot drop-out and dot displacement persist even after you have performed medium
cleaning several times, perform "powerful cleaning."
• This cleaning can be effective when carried out periodically, according to the frequency of use.
