Cleaning the print headB
To ensure good print quality, the machine will 
regularly clean the print head. You can start 
the cleaning process manually if needed.
Clean the print head and ink cartridges if you 
get a horizontal line in the text or graphics on 
your printed pages. You can 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....

After replacing the ink cartridge, check 
the print quality. If the problem still 
exists, repeat the cleaning and test print 
procedures at least five times for the 
new ink cartridge. If ink is still missing, 
call your Brother dealer.
CAUTION 
DO NOT touch the print head. Touching the 
print head may cause permanent damage 
and may void the print heads warranty.
