Cleaning the print head

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.

IMPORTANT

DO NOT touch the print head. Touching the print head may cause permanent damage and may void the print head's warranty.

a Press .

b Press Cleaning.

c Press Black, Color or All.

The machine cleans the print head. When cleaning is finished, the machine will go back to the Ready screen automatically.

Note

If you clean the print head at least five times and the print has not improved, try installing a new genuine Brother Branded 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.
