Replacing the Drum Cartridge
When the drum cartridge is near or reaches the end of its life, the following messages
appear on the printer’s control panel.
WARNING
• Never throw a drum cartridge into an open flame. Toner remaining in the cartridge can
cause an explosion and you can get burnt.
Important
• Make sure that the power is on when replacing the drum cartridge. Switching the power off erases the
print data in the printer and information accumulated in the memory.
• Do not expose the drum cartridge to direct sunlight or strong light.
• Avoid exposure to strong light when installing the drum cartridge and complete the installation in less
than one minute.
• Do not touch the surface of the intermediate transfer belt (black portion on the bottom) or the
photosensitive drum (blue portion on the back side). Do not place the drum cartridge upright or upside
down. Doing so can damage the drum.
• Place the drum cartridge only on a flat surface.
