The “CHANGE DRUM SOON” Message
The “CHANGE DRUM SOON” message is a warning that
the image drum cartridge in your OKIFAX may be
approaching the end of its usable life, which is
approximately 20,000 pages, depending on the length
and type of document you receive or copy. It appears
when the drum has used up approximately 90% of its
life, based on an internal calculation.
This message does not mean that you must replace the
image drum immediately, nor does it cause your
OKIFAX to stop working. In most cases, your image
drum still has at least 10% of its productive life left. You
can continue to use the image drum as long as print
quality is acceptable; however, you should have a
replacement image drum and toner cartridge handy.
Replace the drum when print quality deteriorates below
an acceptable level.
Replacing the Image Drum Cartridge
You need a new image drum if the faxes you receive
are light or have vertical streaks in them and you are
not out of toner, or if your OKIFAX displays a
“CHANGE DRUM” message. Contact your Authorized
OKIFAX Dealer to order one.
Note: You must replace the toner cartridge when you
replace the image drum.
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.
Cautions:
■ Never expose the image drum unit to light for more
than 5 minutes.
■ Never expose the image drum unit to direct sunlight.
■ Never touch the surface of the green drum inside the
image drum unit.
■ Be careful not to scratch the green surface when you
put the drum down on a table or other surface.
To replace the Image Drum Cartridge:
1 Lift the doument table into an upright position.
