Maintenance
Replacing the Image Drum and
Toner Cartridge Simultaneously
Note
● The image drum (the green tube) is very delicate. Handle
it carefully.
● Do not expose the image drum to direct sunlight or very
bright interior light (approximately more than 1,500 lux).
Even under the normal interior light, do not leave it for
more than 5 minutes.
● In order for the printer to exhibit its full performance,
please use genuine Oki Data consumables.
● Service for problems due to use of consumable items
other than genuine OKI consumables will incur fees
even in the warranty period or the maintenance contract
period. (Use of consumable items other than genuine OKI
consumables does not always cause problems, but please
exhibit caution when using those.)
