The attention light is staying on. Drum Life warning came on. All drums replaced. Attention light and drum life warning still on.

This means that one of your drums has exceeded its life cycle (carries toner from the cartridge) and generally run around $100 +/- to replace.

Meaning the life of the k drum is near and you need to replaced it soon or later
other message like below need attention

It means that the black drum is near the end of it useful life. It needs to be replaced.

find the box that the drum came in. There should be directions to reset the drum light enclosed. Or go to www.xerox.com , then look under support and drivers. Good luck !

NOTE: Perform the following procedure to reset the Drum Cartridge counter after you replace the Drum Cartridge. Do not perform this procedure at any other time.

1. From the Standby Mode, press the [Menu] (up arrow) button, then press [5], [2], [0], [4]. The screen will display: Change drum.
   1. Yes
   2. No
2. Press [1], then press [Enter]. The screen will display: Completed.
3. Press [Stop] to return to the Standby Mode.

This is usually a result of a stalling idler pulley or drum, causing a burned spot on the drum drive belt.

The situation will only worsen. The belt is best replaced before it breaks.

Items to pay attention to, when the drum drive belt is replaced, are:
(1) Clean and lube the idler pulley and drum roller shafts.
(2) Confirm that the drum glides will yield additional service life.
(3) Check motor condition and de-lint the blower housing and blower intake pathways.

The figure after the K drum Life tells you how much life there is left on the BLACK (K) drum. C indicates Cyan, M indicates Magenta and Y indicates Yellow.

Go to the USAGE MENU and look at the K DRUM LIFE setting. This will be a 2 digit percentage value. As you have just seen the message appear this will mean that the drum life remaining is ....whatever the 2 digit value displays.

The life expectancy of a drum is approximately 15,000 pages.
