Drum life of e-166 is 72k, so when meter reading reaches to 72,000 maintenance led will turn on.. Thats the time for drum repacement.

If your not satisfied with the copy quality then thats the time you replace the drum and the rest of the consumable parts.72000 is the minimum number of copies only.
