image drum into the printer gently.
7.
Remove the toner cover (orange) of the image drum that is installed in the printer by pressing the tab
in the direction of the arrow.
Memo
Dispose of the toner cover as incombustible waste.
Note
Use caution when removing the toner cover, as there is toner on its back side.
Use extra care when handling the image drum (the green cylinder), because it is fragile.
Do not expose the image drum to direct sunlight or strong light (approximately 1,500 lux or more). Even under room
lighting, when leaving the image drum cartridge for 5 minutes or more, put sheets of paper over it to shield it from the light.
Even with sheets of paper put over the image drum cartridge, do not leave it for one hour or more.
