Cleaning The Print Head; Checking The Print Quality - Brother MFC-685CW User Manual

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 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.
