Replacing the Drum Unit
The machine uses a drum unit to create print images on paper. If the screen displays CHANGE DRUM SOON, the drum unit is near the end of its life and it is time to purchase a new one.
Even if the display shows CHANGE DRUM SOON, you may be able to continue printing without having to replace 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. You should clean the machine when you replace the drum unit. (See page
Caution
When removing the drum unit, handle it carefully because it contains toner. If toner scatters and your hands or clothes get dirty, immediately wipe or wash with cold water.
