Why does the LCD on my machine say 'INK EMPTY' when there is still Ink remaining?
- It is normal to have ink remaining in the cartridge when the MFC displays INK EMPTY. This is necessary to ensure good performance from the print heads and print quality of your work.
- If an ink cartridge is allowed to run dry it could permanently damage the print head, Brother ink cartridges are designed to stop printing before this happens.
- Brother ink cartridges are packaged to compensate for print head maintenance and it does not affect the amount of printed text you would expect to get from the ink cartridges.

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