Toner Cartridge Handling Precautions
Never throw a toner cartridge into an open flame. It can cause an explosion and you can get burnt.
Handling Precautions
■Do not subject it to direct sunlight or strong light.
■When installing the toner cartridge, select a location not subject to strong light and try to finish 
the installation within 5 minutes.
■Do not touch the surface of the photosensitive drum. Do not let the toner cartridge stand or place 
it upside down. The drum might get damaged.
■A drum shutter protects the photosensitive drum from light. Do not open the drum shutter.
■Although the toner is not harmful to the body, wash it off immediately if your hands or clothes 
are stained with it.
■We recommend that you use up the toner cartridge within 1 year after opening it.
■Toner consumption varies according to the image coverage on the page and the print density 
setting.
■The greater the image coverage, the greater the toner consumption.
■If you change the print density setting for lighter or darker printing, toner consumption varies 
accordingly.
■Wait to unpack the toner cartridge until immediately before you install it in the printer.
■Brother strongly recommends that you do not refill the toner cartridge provided with your printer. 
We also strongly recommend that you continue to use only Genuine Brother Brand replacement 
toner cartridges. Using or attempting to use potentially incompatible toner and/or toner 
cartridges in your printer may cause damage to the printer itself and/or it may result in 
unsatisfactory print quality. Our warranty coverage does not apply to any problem that was 
caused by the use of unauthorized third party toner and toner cartridges. To protect your 
investment and guarantee your print quality please continue to replace consumed toner 
cartridges with only Genuine Brother Branded Supplies.
