Deep Print Head Cleaning
If print quality does not improve by the standard cleaning of the print head, clean the print head deeply. Cleaning the print head deeply consumes more ink than the standard cleaning of the print head, so clean the print head deeply only when necessary.
Important
-
When performing the print head deep cleaning, check the free space in the maintenance cartridge. If there is not enough free space, replace with the new maintenance cartridge. In the case of shortage of free space in the maintenance cartridge, a message is displayed and the cleaning cannot be performed.
Note
-
You can also clean the print head deeply using the computer. When using the computer, select the ink group to clean, then start cleaning.
