When Normal Cleaning Is Not Effective

Powerful 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 medium cleaning, perform the more forceful
"powerful cleaning" to remove clogging from the print heads.
P. 138「Medium Cleaning Method」
IMPORTANT
Powerful cleaning consumes more ink than medium cleaning, and overly frequent use may damage the print heads themselves. Avoid
performing this operation more than necessary.
1.
Prepare for powerful cleaning.
After determining the group of print heads on which to perform powerful cleaning, dispose of the discharged fluid
