The Black toner cartridge yields up to 10, 000 pages while each of the color toner cartridges yield up to 6, 600 pages when printing at 5% coverage on A4/Letter sized paper. When one of the LCD panel squares starts to flash, this indicates that one of the toner cartridges is running low on toner. When this happens, you should order the appropriate replacement toner from your Brother reseller as soon as possible. When you see "TONER EMPTY" message on the LCD panel, the printer stops printing until you replace the toner cartridge which has run out.
