Cleaning The Print Head; Checking The Print Quality - Brother MFC-J625DW Basic User's Manual

Cleaning the print head

To maintain good print quality, the machine
will automatically clean the print head when
needed. You can start the cleaning process
manually if there is a print quality problem.
Clean the print head if you get a horizontal
line in the text or graphics, or blank text 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.
IMPORTANT
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™ ink cartridge for each problem
color. Try cleaning the print head again up
to five more times. If the print has not
improved call your Brother dealer.
