100 Replacing the consumable itemsC You will need to replace the consumable items when the machine indicates that the life of the consumable is over. IMPORTANT • We recommend placing used consumable items on a sheet of paper to prevent accidentally spilling or scattering the material inside. • Be sure to reseal the consumable items tightly so that the material inside does not spill. Note • Go to http://www.brother.com/original/index.html for instructions on how to return your used consumable items to the Brother collection program. If you choose not to return your used consumable, please discard the used consumable according to local regulations, keeping it separate from domestic waste. If you have questions, call your local waste disposal office. • If you use paper that is not a direct equivalent for the recommended paper, the life of consumable items and machine parts may be reduced.

Troubleshooting and routine maintenance 101 C Replacing a toner cartridgeC The High Yield toner cartridges can print approximately 8,000 pages 1 and the Standard toner cartridges can print approximately 3,000 pages 1. Actual page count will vary depending on your average type of document (i.e., standard letter, detailed graphics). The machine is supplied with the TN-620 toner cartridge that will need to be replaced after approximately 3,000 pages 1. When a toner cartridge is running low, the LCD shows Toner Low. 1Approx. cartridge yield is declared in accordance with ISO/IEC 19752. Note It is a good idea to keep a new toner cartridge ready for use when you see the Toner Low warning. CAUTION HOT SURFACE After 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. aPress the front cover release button and open the front cover. bSlowly take out the drum unit and toner cartridge assembly.

102 cPush down the blue lock lever and take the used toner cartridge out of the drum unit. WARNING DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries. IMPORTANT • Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once. • To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations. • Brother strongly recommends that you DO NOT refill the toner cartridge provided with your machine. We also strongly recommend that you continue to use only Genuine Brother Brand replacement toner cartridges. Use or attempted use of potentially incompatible toner and/or cartridges in the Brother machine may cause damage to the machine and/or may result in unsatisfactory print quality. Our warranty coverage does not apply to any problem that is caused by the use of unauthorized third party toner and/or cartridges. To protect your investment and obtain premium performance from the Brother machine, we strongly recommend the use of Genuine Brother Supplies. • Wait to unpack the new toner cartridge until immediately before you put it in the machine. If a toner cartridge is left unpacked for a long time, the toner life will be shortened. • Be sure to seal up the used toner cartridge tightly in a suitable bag so that toner powder does not spill out of the cartridge. dUnpack the new toner cartridge. Gently shake it from side to side several times to distribute the toner evenly inside the cartridge. ePull off the protective cover. fPut the new toner cartridge firmly into the drum unit until you hear it lock into place. If you put it in properly, the lock lever will lift automatically.
Troubleshooting and routine maintenance 103 C Note Make sure that you put in the toner cartridge properly or it may separate from the drum unit. gClean the corona wire of the drum unit by gently sliding the blue tab from right to left and left to right several times. Note Be sure to return the blue tab to the home position (a) (1). If you do not, printed pages may have a vertical stripe. hPut the drum unit and toner cartridge assembly back in the machine. iClose the front cover. Note DO NOT turn off the machine’s power switch or open the front cover until the LCD returns to the standby state. Replacing the drum unitC 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 on page 95.) 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. 1Drum yield is approximate, and may vary by type of use. 1
