Replacing the Image Drum Unit
If the faxes you receive are light or have vertical
streaks in them and you are not out of toner, or
if your fax machine displays a CHANGE DRUM
message, your fax machine needs a new image
drum unit. Contact your dealer to order one.
The life of an image drum depends on a number of fac-
tors, 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.
