(See Replacing the Drum Unit, Page 13-23.) 4Close the front cover. 5Plug in the power cord first, and then plug in the telephone cord. Replacing the Toner Cartridge The machine can print up to 6,000 pages using a high yield toner cartridge. When the toner cartridge is running low, the display shows TONER LOW. The machine is supplied with a standard toner cartridge that must be replaced after approximately 3,000 pages. Actual page count will vary depending on your average document type (i.e., standard letter, detailed graphics). 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 machine when you replace the toner cartridge. Toner Empty Indicator When the toner cartridge is running low, the LCD shows TONER LOW and the Toner Empty icon on the control panel flashes on and off to indicate the toner is low. The Toner Empty icon appears and the LCD shows TONER EMPTY. Once this icon appears, your machine will not resume printing until you install a new toner cartridge. LCDToner Empty Icon

13 - 22 TROUBLESHOOTING AND ROUTINE MAINTENANCE Caution Wait to unpack the toner cartridge until immediately before you install it into the machine. If a toner cartridge is left unpacked for a long period of time, the toner life is shortened. You can use only a genuine Brother Toner Cartridge (TN-430 or TN-460), which is specially formulated to ensure top print quality. Using another brand of toner cartridge may void your machine’s warranty. Warranty coverage does not apply to problems caused by the use of 3rd party Toner, 3rd party Toner cartridge or 3rd party Drum unit. 4Gently rock the toner cartridge from side to side five or six times to distribute the toner evenly inside the cartridge. 5Remove the protective cover. 6Install the new toner cartridge into the drum unit until it clicks into place. 7Clean the primary corona wire inside the drum unit by gently sliding the blue tab from right to left several times.

TROUBLESHOOTING AND ROUTINE MAINTENANCE 13 - 23 8Reinstall the drum unit and close the front cover. Replacing the Drum Unit The machine uses a drum unit to create print images on paper. If the LCD shows CHANGE DRUM SOON, the drum unit is near the end of its life and it is time to purchase a new one. Even if the LCD shows CHANGE DRUM SOON, you may be able to continue printing without having to replace the drum unit for a while. However, if there is a noticeable deterioration in the output print quality (even before CHANGE DRUM SOON is shown), then the drum unit should be replaced. You should clean the machine when you replace the drum unit. (See Page 13-19.) Caution When removing the drum unit, handle it carefully because it contains toner. If toner scatters and your hands or clothes get dirty, immediately wipe or wash with cold water. WARNING Just after you have used the machine, some internal parts of the machine are extremely HOT! So please be careful. Follow these steps to replace the drum unit: The drum unit is a consumable item, and it is necessary to replace it periodically. There are many factors that determine the actual drum life, such as temperature, humidity, type of paper and how much toner you use for the number of pages per print job. The estimated drum life is up to 20,000 pages. The actual number of pages your drum will print may be significantly less than these estimates. Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum. HOT!
