Brother strongly recommends that customers use only genuine Brother ink for best results. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability since the ink formulation in genuine Brother ink cartridges prevent smearing and clogging of the print head. The Brother limited warranty does not apply to any problem that was caused by the use of third party ink and/or cartridges.

Checking the print quality and cleaning the print head
If faded or streaked text appear on your printouts, some of the print head nozzles may be clogged. You can check this by printing the test page and looking at the nozzle check pattern.
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 vertical line in the text or graphics, or blank text on your printed pages. Cleaning the print head consumes ink. Cleaning too often uses ink unnecessarily.
DO NOT touch the print head. Touching the print head may cause permanent damage and may void the print head's warranty.
If the machine is left unplugged for a long period of time, it will automatically start cleaning when you plug the machine back in. This cleaning process will reduce the rated life of the ink cartridge in the machine.
If you clean three times and the print has not improved, the LCD will ask you to start Advanced Cleaning. To start Advanced Cleaning, press 1 to choose Yes then go to step 4 in Advanced Cleaning. To finish the cleaning, press 2 to choose No.
Advanced Cleaning
Cleans the print head more thoroughly than Cleaning Wizard. Choose this option if Cleaning Wizard does not clean the print head adequately, when the print appears thin, or when there are smudges.
If you have cleaned three times and the print has not improved, the LCD will tell you to call for a service. Press OK and please contact Brother Customer Service from the "Contact Us" section.
