Drum Life Considerations for Your Brother Machine Your Brother machine uses a drum and toner assembly for document printing. The toner life is directly dependent upon the amount of black printing on the printed pages. The estimated drum life is up to 20,000 A4 sized pages. Maintaining quality print during this period will depend on factors such as the number of pages printed per day, time between print jobs, the quality of the printing paper and the environment in which the machine is used. The drum unit (DR-6000) is a consumable and to maintain an acceptable printing quality it should be replaced at the end of it's 20,000 A4 page life. Printing quality is a subjective issue and the drum should be replaced at a time when the printing quality becomes unacceptable to the user in relation to the documents being printed. The print quality will deteriorate over time and replacing the drum will return the printing quality to its optimum level. In order to maintain optimum print quality, we also recommend that the drum is replaced after 18 months service. To assist you, the machine will advise when approximately 5-15% of the drum life remains by showing the message CHANGE DRUM SOON on the display. This indication takes the number of pages printed and the total printing time into consideration. When the message appears we advise that a new drum be obtained for replacement at a convenient future time. 1 To check the remaining drum life, press Menu/Set, 1, 5. 2 The following indication appears on the LCD for 5 sec, and the display returns automatically to GENERAL SETUP menu. DRUM LIFE REMAINING:###% 3 Press Stop. We emphasise that even if the drum life remaining indicates 0%, you only need to replace the drum if the print quality is unacceptable. By using a drum past the 0% indication no damage will be caused to the machine and whilst the print quality remains acceptable then the drum may be used beyond its designed life. Replacing the Drum Unit The machine uses a drum unit to create the print images on paper. If the screen displays CHANGE DRUM SOON, the drum unit is nearly at the end of its life. Prepare a new drum unit to replace the current one. You may need to order one from your Brother dealer. Even if the display shows CHANGE DRUM SOON, you may be able to continue to print without replacing the drum unit for a while. However, if there is a noticeable deterioration in the output print quality even before CHANGE DRUM SOON is shown, then the drum unit should be replaced. You should clean the machine when you replace the drum unit. When removing the drum unit, handle carefully because it contains toner. When you replace the drum unit, you should clean the machine. 88 Chapter 9
