Replacing the Image Drum Unit (OKI P/N 40709901)
If the faxes you receive are light or have vertical streaks in them and you
are not out of toner, or if your MFP machine displays a CHANGE DRUM
message, your MFP machine needs a new image drum unit. Contact your
dealer to order one.
The life of an image drum depends on a number of factors, including
temperature and humidity, the type of paper you use, and the number of
pages per job. The image drum cartridge should last about 10,000 pages
for continuous printing, up to 8,000 pages at 3 pages per job, and about
4,500 pages at 1 page per job.
Warning: Never expose the image drum unit to light for more than
5 minutes. Never expose the image drum unit to direct
sunlight. Always hold the image drum unit by the ends.
Never touch the surface of the green drum inside the
image drum unit.
CAUTION: If you open the top cover, you will see a label that reads:
(CAUTION-HOT).
This portion is extremely hot and must not be
touched under any circumstances.
1 Lift the MFP machine’s top cover and swing it out of the way.
