the image drum. Repeat this procedure several times and then
check again if you still have dirty print-outs. If this procedure
does not solve the problem, your fax machine needs a new image
drum unit. Contact your dealer to order one.

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

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.

Caution: 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.
