[. . . ] 5-4 5-7 ! Caution · · · · Wait to unpack the Toner Cartridge until immediately before you put it in the printer. If Toner Cartridges are left unpacked for a long time, the toner will not last as long as it should. If an unpacked Drum Unit is put in direct sunlight or room light, the unit may be damaged. Use a genuine Brother Toner Cartridge that is specially formulated for high-quality printing. Printing with a toner or a toner cartridge that is not made by Brother may reduce the print quality and the quality and life of the printer itself. It may also cause serious damage to the performance and life of a drum unit. The warranty does not cover problems caused by using other toners, toner cartridges or drum units. 5 Remove the protective cover. Fig. 5-5 ! Caution Put in the Toner Cartridge immediately after you remove the protective cover. Do not touch the shaded parts shown below as this may affect print quality. 5-8 CHAPTER 5 MAINTENANCE 6.

CHANGE DRUM SOON Message CHANGE DRUM SOON The printer uses a Drum Unit to create the print images on paper. If the display shows the above message, it means the Drum Unit is near the end of its life. We recommend that you replace the Drum Unit with a new one before there is a noticeable deterioration in the print quality. ! Replacing the Drum Unit This printer can print upto 20, 000 pages *1 with one Drum Unit. *1 At 5% coverage print (A4-Letter size). The actual number of printed pages may vary depending on the average type of print job and paper. Note There are many things that affect how long the drum unit lasts for, such as the temperature, humidity, type of paper, type of toner used, the number of pages in each print job and so on. Under ideal conditions, a drum unit will last for upto 20, 000 pages. The actual number of pages that your drum will print may be significantly less than this estimate. Because we have no control over the many things that affect the actual drum life, we cannot guarantee a minimum number of pages that your drum will print.
