Replacing the Toner Cartridges (TN-12BK/Y/M/C)

The printer uses four toner cartridges: black, yellow, magenta and cyan. When the toner supply in a
cartridge begins to run out, the message Replace xxxx Toner (x) message appears on the
operation panel (xxxx is the toner cartridge color). Replace toner cartridge(s) as soon as the message
prompting you to do so appears. The printer will stop operating if you do not replace the toner cartridge
when required.
Toner cartridges are consumables. For more information about consumables, see Introduction to the
Optional and Consumable Items on page A-1.
For details about when to change consumables, see Life Span of Consumable Items on page A-9.

Toner Cartridge Handling Precautions

WARNING
Never throw a used toner cartridge into a fire. It can explode, causing injuries.
Handling Precautions
■Never use a vacuum cleaner to clean toner. Static electricity could build up and damage
sensors.
■Do not reuse toner cartridges once you have removed them from the printer. Loose toner could
spill inside the printer and deteriorate print quality.
■To prevent residual toner form spilling, avoid shaking or bumping used toner cartridges.
■After moving a toner cartridge from a cold place to a warm place, allow 1 hour for the cartridge
to adapt to room temperature before installing it. (This is not necessary if there is no
condensation.)
■Toner should be washed off immediately if it gets on your hands or clothing.
■Only use toner cartridges recommended by Brother. Using toner cartridges that are not
recommended may result in lower print quality and unsatisfactory printer performance.
Storage Precautions
■Store cartridges away from direct sunlight under the following conditions:
■Ambient temperature range, 0 to 35 °C. Humidity range 15 to 80% RH (no condensation). Avoid
hot and humid areas.
■Avoid storing near magnetic objects such as CRT screens, disk drives, or floppy disks.
■Keep out of reach of children.
