Performing Normal Cleaning

Procedure
1.
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.
