If the Drum LED is on, it indicates the drum unit is nearly at the end of its life. Even if the Drum LED is on, you may be able to continue to print without replacing the drum unit for a while. If there is a noticeable deterioration in the output print quality even before the Drum LED lights, then the drum unit should be replaced. Drum Ready Paper Alarm Toner Data Fig. 3-12 Drum unit nearly at the end of its Life · When removing the drum unit, handle it carefully as it may contain toner. See "How to clean the printer" in this chapter and in the instructional video on the supplied CD-ROM. ! Caution Note · The drum unit is a consumable, and it is necessary to replace it periodically. · There are many factors that determine the actual drum life, such as temperature, humidity, type of paper and toner that you use, the number of pages per print job, etc. Under ideal conditions, the average drum life is estimated at approximately 20, 000 pages. The actual number of pages that your drum will print may be significantly less than this estimate. Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum. The product should only be used in a clean, dust-free environment with adequate ventilation. 3-9 Follow these steps to replace the drum unit. You can also view the drum unit replacement method in the instructional video on the supplied CD-ROM: 1. Open the front cover of the printer and pull out the drum unit assembly.
