To maintain print quality, the machine will automatically clean the print head. You can start the cleaning process manually if there is a print quality problem.
Clean the print head and ink cartridges if you get a horizontal line or blank text in the text or graphics on your printed pages. You can clean Black only, three colours at a time (Cyan/Yellow/Magenta), or all four colours at once.
Cleaning the print head consumes ink. Cleaning too often uses ink unnecessarily.
CAUTION
DO NOT touch the print head. Touching the print head may cause permanent damage and may void the print head's warranty.

Note
If you clean the print head at least five times and the print has not improved, try installing a new Brother original Innobella™ replacement cartridge for each problem colour. Try cleaning the print head again up to five more times. If the print has not improved call your Brother dealer.
