CHAPTER TWO

Choosing a Location

Place your MFC on a flat, stable surface, such as a desk. Select a place
that is free of vibration and shocks. Locate the MFC near a standard,
earthed electrical socket. Choose a location where the temperature
remains between 10°C and 32.5°C.

Avoid placing your MFC where it may be knocked. Do not place near
heaters, air conditioners, water, chemicals, or refrigerators. Do not
expose the MFC to direct sunlight, excessive heat, moisture, or dust. Do
not connect your MFC to electrical outlets on the same circuit as large
appliances or other equipment that might disrupt the power supply. Avoid
interference sources, such as speakers or the base units of cordless
phones. Ensure the airflow from the fan on the right hand side of the
MFC is not impeded.

Caution

Keep the MFC out of strong light such as direct sunlight.

For Your Safety

To ensure safe operation the three-pin plug supplied must be inserted
only into a standard three-pin power point which is effectively grounded
through the normal household wiring.

The fact that the equipment operates satisfactorily does not imply that
the power is grounded and that the installation is completely safe. For
your safety, if in any doubt about the effective grounding of the power,
consult a qualified electrician.

IEC 825 Laser Class

CLASS 1 LASER PRODUCT.

Disconnect device

The equipment must be installed near the socket outlet which must be
easily accessible.

IMPORTANT

If the socket outlet is not compatible with the mains plug as fitted, then
remove the plug from the mains cord and fit an appropriate three pin
plug. If the replacement plug is intended to take a fuse then fit with the
same fuse rating as the original.

If a moulded plug is severed from the power cord then it should be
destroyed because a plug with cut wires is dangerous if plugged into a
live socket outlet. Do not leave it where a child might find it.

In the event of replacing the plug fuse, fit a fuse approved by ASTA to
BS1362 with the same rating as the original fuse.

Always replace the fuse cover. Never use a plug with the cover omitted.
WARNING - THIS PRINTER MUST BE PROPERLY EARTHED.
The wires in the supplied main cord are the following colours.

Green and yellow: Ground
Blue: Neutral
Brown: Live

Replacing the Toner Cartridge

The machine can print up to 6,000 pages using a high yield toner
cartridge (TN-6600). When the toner cartridge is running low, the
display shows CHANGE TONER. The machine is supplied with a
standard toner cartridge (TN-6300) that must be replaced after
approximately 3,000 pages. Actual page count will vary depending on
your average document type.

It is a good idea to keep a new toner cartridge ready for use when you
see the toner low warning.

Discard the used toner cartridge according to local regulations. If you are
not sure of them, consult with Brother dealer for service. Be sure to seal
the toner cartridge tightly so toner powder does not spill out of the
cartridge. When discarding used toner cartridges, keep them separate
from domestic waste.

It is recommended that you clean the machine when you replace the
toner.

CHAPTER EIGHT

Drum Life Considerations for Y our 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 drum will last for 77 hours of
continuous printing time, which in normal use will be 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 or
77 hours 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.

Press Stop to exit.

4

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.
