Description: The magenta toner cartridge has almost reached its estimated cartridge life. The machine might stop printing.
Remedy: If Stop, Continue or Mono Only appears in the LCD display, choose one of them. If you select Stop, the machine stops printing and you cannot print anymore without changing the cartridge. If you select Continue, the machine keeps printing but the printing quality cannot be guaranteed. If you select Mono Only, the machine prints the data in black only. Replace the toner cartridge for the best print quality when this message appears. Using a cartridge beyond this stage can result in printing quality issues.
