See the section "Replacing the Drum Unit" in this chapter. 5 Close the top cover. 6 Plug in the power cord. 7 Connect the telephone line. Replacing the Toner Cartridge The machine can print approximately 2,200 pages with one toner cartridge. When the toner cartridge is running low, the display shows CHANGE TONER. 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 with Brother dealer for 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. It is recommended that you clean the machine when you replace the toner. Toner Empty Indicator When the toner cartridge is running low, the display shows CHANGE TONER and the Toner Empty LED on the control panel flashes on and off to indicate the toner is low.
