1
Power off this machine.
2
Press the front cover open button on the side of this machine and open the front cover toward
you.
3
Hold the toner cartridge, push it up a little, and then pull it out toward you. Remove the toner
cartridge with the image drum attached.
Do not touch the blue lever on the toner cartridge.
Handle with adequate care since the green part of the image drum is very easy to be damaged.
Do not expose the image drum to direct sunlight or strong light (approx. 1,500 lux or above). Do not leave it
uncovered for more than 5 minutes even under room lighting.
4
Place the removed toner cartridge and image drum on a flat surface covered with newspaper or
the like, and cover them with paper to avoid direct light.
