      Clayton MayAug 25, 2025
      If your Brother All in One Printer is only printing in B&W 1-sided and prompts you to replace ink, it indicates that one or more of the color ink cartridges have reached the end of their life. Replace the ink cartridges, as the machine will stop all print operations until a new ink cartridge is installed.
