Chapter 11 Replacing the toner cartridge (TN-350) The toner cartridge can print up to 2,500 pages. When the toner cartridge is running low, the LCD shows Toner Low. 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 the toner cartridge tightly so 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 MFC and drum unit when you replace the toner cartridge. (See Cleaning the laser scanner window on page 11-23 and Cleaning the drum unit on page 11-17.) How to replace the toner cartridge WARNING Just after you use the MFC, some internal parts of the machine will be extremely HOT! Never touch the shaded parts shown in the illustration. 1 Open the front cover and pull out the drum unit and toner cartridge assembly. CAUTION To prevent damage to the MFC from static electricity, do not touch the electrodes shown below. 11 - 25
