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. If you are not sure of them, consult Brother Customer Service. Be sure to seal the toner cartridge tightly so toner powder does not spill out of the cartridge. When discarding used toner cartridges, keep them separate from domestic garbage. We recommend that you clean the machine when you replace the toner cartridge.

If the screen displays 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 display 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 17-22.) 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. The drum unit is a consumable, 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, etc. 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. WARNING Just after you have used HOT!the machine, some internal parts of the machine are extremely HOT! So please be careful.
