• This product is equipped with a 3-wire grounded plug. This plug will only fit into a
grounded power outlet. This is a safety feature. DO NOT attempt to defeat the purpose
of the grounded plug.
• DO NOT pull on the middle of the AC power cord; pulling on the middle may cause the
cord to separate from the plug. Doing this might cause an electrical shock.
• Only use the power cord supplied with this product (for certain models only).
• DO NOT use any undesignated cables (or optional devices). It may cause a fire or
injuries. Installation must be performed properly according to the user's guide.
• This product should be positioned so that nothing pinches or constricts the power cord.
• DO NOT allow anything to rest on the power cord.
• DO NOT place this product where people may step on the cord.
• DO NOT place this product in a position where the cord is stretched or strained, as it
may become worn or frayed.
• DO NOT use the product if the power cord is frayed or damaged. Doing so may cause
an electrical shock or fire.
• Brother strongly recommends that you DO NOT use any type of extension cord.
• DO NOT drop any metallic hardware or any type of liquid on the power plug of the
product. It may cause an electrical shock or a fire.
DO NOT put a toner cartridge or a toner cartridge and drum unit assembly into a fire. It
could explode, resulting in injuries.
DO NOT use flammable substances, any type of spray, or an organic solvent/liquid
containing alcohol or ammonia to clean the inside or outside of the product. Doing so

clean the toner dust with a dry, lint-free soft cloth and dispose of it according to local
regulations.
