New Toner Cartridge Drum Unit Scanner Cover Drum Unit Replacing the Drum Unit The DCP uses a drum unit to create the print images on paper. If the LCD shows CHANGE DRUM SOON, the drum unit is near the end of its life. Purchase a new drum unit to replace the current one. Even if the LCD shows CHANGE DRUM SOON, you may be able to continue to print without replacing 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.

If toner scatters and your hands or clothes get dirty, immediately wipe or wash with cold water. The drum unit is a consumable item, 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 and 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 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 a genuine Brother toner cartridge. The product should be used only in a clean, dust-free environment with adequate ventilation.
