Replacing the toner cartridge (TN-550/TN-580) C The TN-580 toner cartridge can print approximately 7,000 pages using a high yield toner cartridge. When the toner cartridge is running low, the LCD shows Toner Low. The machine is supplied with a standard TN550 toner cartridge that must be replaced after approximately 3,500 pages. Actual page count will vary depending on your average type of document (i.e., standard letter, detailed graphics). Note It is a good idea to keep a new toner cartridge ready for use when you see the Toner Low warning. Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste. Be sure to seal up the toner cartridge tightly so that toner powder does not spill out of the cartridge. If you have questions, call your local waste disposal office. We recommend that you clean the machine and corona wire of the drum unit when you replace the toner cartridge. (See Cleaning the laser scanner window on page 128 and Cleaning the corona wire on page 130.)
