The machine uses a drum unit to create print images on paper. If the LCD shows
Replace 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 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 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. |


CAUTION
| HOT SURFACEAfter you have just used the machine, some internal parts of the machine will be extremely hot. To prevent injury, when you open the front or back cover (back output tray) of the machine DO NOT touch the shaded parts shown in the illustration. If you do this you may get burned. |

3 | Push down the blue lock lever and take the toner cartridge out of the drum unit.   IMPORTANT • | To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations. | • | Wait to unpack a new drum unit until immediately before you put it in the machine. Exposure to direct sunlight or room light may damage the drum unit. | • | Be sure to seal up the used drum unit tightly in a bag so that toner powder does not spill out of the unit. |
