Drum unit This printer can print up to 30,000 pages* with one drum unit. * At 5% print coverage (A4 or Letter size). The actual number of printed pages will vary depending on the average type of print job and paper. ■ There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used, number of pages per print job and so on. Under ideal conditions, the average drum life is estimated at up to 30,000 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. ■ For best performance, use only genuine Brother toner. The printer should be used only in a clean, dust-free environment with adequate ventilation. ■ Printing with a third-party drum unit may reduce not only the print quality but also the quality and life of the printer itself. Warranty coverage does not apply to problems caused by the use of third-party drum unit. CHANGE DRUM SOON message CHANGE DRUM SOON The printer uses a drum unit to create the print images on paper. If the LCD shows CHANGE DRUM SOON, it means the drum unit is near the end of its life. We recommend that you replace the drum unit with a new one before there is a noticeable deterioration in the print quality. Replacing the drum unit Caution While removing the drum unit, handle it carefully because it may contain toner. We recommend that you clean the printer when you replace the drum unit. See Cleaning on page 5-14. 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: 5 - 8 ROUTINE MAINTENANCE
