OKI fax 5050 User Manual

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.

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.

You must replace the toner cartridge when you

replace the image drum.

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.

■

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:

Lift the doument table into an upright position.
