It appears when thedrum has used up approximately 90% of its life, based on aninternal calculation.This message does not mean that you must replace the imagedrum immediately, nor does it cause your fax machine 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. Replace the drum when print qualitydeteriorates below an acceptable level.
