Clean the Print Head from Your Brother Machine
To maintain good print quality, the machine automatically cleans the print head when needed. If there is a print
quality problem, start the cleaning process manually.
• Clean the print head if there is a horizontal line or a blank space in the text or graphics on printed pages.
Depending on the problem colour, select to clean Black only, three colours at a time (Yellow/Cyan/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.
