If the Drum lamp is on, it indicates the drum unit is nearly at the end of its life. Even if the Drum lamp 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 lamp lights, then the drum unit should be replaced. Dru m Alar m Pap dy er Rea Ton a er Dat Fig. 5-11 Drum Unit Nearly at the End of its Life ! Caution When removing the drum unit, handle it carefully as it may contain toner. 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. . The drum life is estimated at approximately 20, 000 pages at 20 pages per job and 8, 000 pages at 1 page per job. The actual number of pages that your drum will print may be significantly less than these estimates. 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, and the product should only be used in a clean, dust-free environment with adequate ventilation. 5-7 USER'S GUIDE Follow these steps to replace the drum unit: 1. 5-12 Removing the Drum Unit Warning After you have just used the printer, some internal parts of the printer are extremely hot.

High Temperature Fig. Remove the toner cartridge from the drum unit and keep it in a safe place. For more information, see "REPLACING THE TONER CARTRIDGE" in this chapter. Be sure to seal up the drum unit tightly so that toner powder does not spill out of the unit. It is recommended to put the drum unit on a piece of disposable paper or cloth in case of accidental toner spill or scatter. 5-8 CHAPTER 5 MAINTENANCE Fig. [. . . ] In the event of replacing the plug fuse, fit a fuse approved by ASTA to BS1362 with the same rating as the original fuse. The wires in the mains cord are coloured in accordance with the following code: Green and yellow: Blue: Brown: Ground Neutral Live The colours of the wiring in the power lead of this printer may not correspond with the markings which identify the terminals in your plug. Remove a length of the cord outer sheath, taking care not to damage the coloured insulation of the wires inside. If the construction of the plug permits, leave the green and yellow wire longer than the others so that, in the event that the cord is pulled out of the plug, the green and yellow wire will be the last to disconnect.
