  When the message 'Replace new cartridge' appears on your Samsung All in One Printer, it means the toner cartridge is nearing its estimated end of life. You can either stop printing and replace the cartridge, or continue printing. Note that if you continue printing, the quality is not guaranteed. For the best print quality, replace the toner cartridge when this message appears. Keep in mind that using a cartridge beyond this stage can lead to printing quality issues.
