It appears when the drum has used upapproximately 90% of its life, based on an internal calculation.This message does not mean that you must replace the imagedrum immediately, nor does it cause your OKIFAX to stopworking. In most cases, your image drum still has at least10% of its productive life left. You can continue to use theimage drum as long as print quality is acceptable; however,you should have a replacement image drum and tonercartridge handy.
