Improve poor print quality.

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 issue that was caused by the use of third party ink and/or cartridges.
