Replacing the drum unit
The machine uses a drum unit to create print images on paper. If the LCD shows Replace Parts Drum, the drum unit is near the end of its life and it is time to buy a new one. Even if the LCD shows Replace Parts Drum, you may be able to continue printing without having to replace the drum unit for a while. However, if there is a noticeable deterioration in the output print quality (even before Replace Parts Drum appears), then the drum unit should be replaced. You should clean the machine when you replace the drum unit. (See Cleaning the laser scanner window
IMPORTANT
While removing the drum unit, handle it carefully because it may contain toner. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
Note
The drum unit is a consumable item, 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 how much toner you use for the number of pages per print job. The estimated drum life is
approximately 25,000 pages 1. The actual number of pages 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.
