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

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.
