CHAPTER 5 ROUTINE MAINTENANCE

4. Unpack the new toner cartridge. Keeping the cartridge horizontal, gently rock it from side to side five or six times.

!Caution

Wait to unpack the toner cartridge until immediately before you install it in the printer. If toner cartridges are left unpacked for a long period of time the toner life will be shortened.

If an unpacked drum unit is subjected to excessive direct sunlight or room light, the unit may be damaged.

Use a genuine Brother toner cartridge that is specially formulated to ensure optimum print quality.

Printing with a 3rd party toner or 3rd party toner cartridge may reduce not only the print quality but also the quality and life of the printer itself. It may also cause serious damage to the performance and life of a drum unit. Warranty coverage does not apply to problems caused by the use of 3rd party toner or 3rd party toner cartridges.
