Drum unit

A new drum unit can print approximately 12,000 A4 or Letter size single-sided pages at 1 per/ job.

Note

•	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 approximately 12,000 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 a third-party drum unit.

Change Drum message

The Drum LED will turn on for 2 seconds and off for 3 seconds and repeats this pattern.

If the LED shows the message, 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.
	Every time you replace the drum unit, clean the inside of the printer. See Cleaning.

When you replace the drum unit with a new one, you need to reset the drum counter by completing the following steps:

Make sure that the printer is turned on and the Drum LED is blinking. Open the front cover.

Press and hold down the white Go button for about 4 seconds until all the LEDs light up. Once all four LEDs are lit, release the Go button.

Improper Setup

Do not reset the drum counter when you only replace the toner cartridge.

Take out the drum unit and toner cartridge assembly.

CAUTION

	We recommend that you put the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
	To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the illustration.

Push down the green lock lever and take the toner cartridge out of the drum unit.

CAUTION

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.

Note

•	Be sure to seal up the drum unit tightly in a suitable bag so that toner powder does not spill out of the unit.
•	Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste. If you have questions, call your local waste disposal office.

Unpack the new drum unit.

CAUTION

Wait to unpack a drum unit until immediately before you put it in the printer. Exposure to direct sunlight or room light may damage the drum unit.

Put the toner cartridge firmly into the new drum unit until you hear it lock into place. If you put the cartridge in properly, the green lock lever will lift automatically.

CAUTION

Make sure that you put in the toner cartridge properly, or it may separate from the drum unit.

Put the drum unit and toner cartridge assembly back in the printer.

Close the front cover.

Make sure that the Drum LED is now off.
