Replace the toner cartridges Replace the toner cartridges if you receive a message on the printer, or if you are having print quality problems. Toner-cartridge information Review details about ordering replacement toner cartridges. The printer indicates when the toner-cartridge level is low and very low. The actual toner-cartridge life remaining can vary. Consider having a replacement cartridge available to install when print quality is no longer acceptable. Continue printing with the current cartridge until redistributing the toner no longer yields acceptable print quality. To redistribute the toner, remove the toner cartridge from the printer and gently rock the cartridge back and forth end to end. Reinsert the toner cartridge into the printer and close the cover.
