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.
Note
- When cleaning the print head deeply using the operation panel, the print head of all ink colors are cleaned.
What you will need: a sheet of A4 or Letter-sized plain paper
