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.
Procedure
1.
Load the media.

Check for the group with dot drop-out or dot displacement by viewing the results of the printing test.
The space from "A" to "B" is group A. The space from "B" to the right side is group B.
MEMO
If the printing-test results are difficult to interpret
• Check the results in a bright location, changing your line of vision. They are visible using the reflection of
the light.
• Depending on the media, locations on which optimizer ink is printed may be difficult to check. If it is diffi-
cult to see the optimizer ink, switch to a different media and perform the printing test again.
