CHAPTER 6 MAINTENANCE
REPLACING THE DRUM UNIT
The machine uses a drum unit to create the print images on paper. If the Drum lamp is on, it indicates the drum unit is nearly at the end of its life. We recommend you prepare a new drum unit to replace the current one. Even if the Drum lamp is on, you may be able to continue to print without replacing the drum unit for a while. If there is a noticeable deterioration in the output print quality even before the Drum lamp lights, then the drum unit should be replaced.

!Caution
When removing the drum unit, handle it carefully as it contains toner. You should clean the machine when you replace the drum unit. See “CLEANING THE MACHINE” in this chapter.
✒Note
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 toner that you use, the number of pages per print job, etc.. The drum life is estimated at approximately 20,000 pages at 20 pages per job and 8,000 pages at 1 page per job. The actual number of pages that 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.
For best performance, use only genuine Brother toner and use the product in a clean,
