A:Answer If one or more color ink cartridges are low, but not at the end of their usable life and you want to minimize the use of color ink, change the settings in the Brother software to print with black ink only (grayscale). If you print with black ink only, the other ink cartridges must have ink for the printer to print. When an ink cartridge is depleted, you must replace it before you can print.
If you print with black ink only, the printer may still use small amounts of ink from all the ink cartridges for occasional servicing tasks. Brother recommends that you replace any low ink cartridges to avoid any interruptions in printing.
