Replacing the Drum Cartridge
The following messages appear on the display when the drum cartridge is near the end of
its life.
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 switched 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.
Replacement Procedure
Follow these steps to replace the drum cartridge and to clean inside the printer.
1. If paper is loaded in the bypass tray,
remove the paper and close the bypass
tray cover.
Important
• When closing the bypass tray cover, be careful not to
get your fingers caught between (the left or right edge
of) the cover and the printer.
