Print using only the black ink tank when the Color tanks have run out.
Basically, your Brother machine is designed to stop ALL printing operations when any of the ink tanks (except black) are low. This is to ensure the life of the print head and maintain premium print quality. If the unit were to continue printing, print jobs and cleaning cycles would damage the print head.
However, your Brother machine exceptionally can operate in a B&W Print Only (black and white) mode when one or more color ink tanks are low. When a color tank is low, an error message will appear on the machine's display (hereinafter called LCD) of the machine stating B&W Print Only.
