This printer may interfere with radio or television reception, causing flickering or distortion. This can be
determined by turning the printer off and on. To correct interference, perform one or a combination of the
following procedures:
■
Move the printer away from a TV and/or radio.
■
Reposition the printer, TV and/or radio.
■
If the printer, TV and/or radio are plugged to the same AC power outlet/socket, unplug them, then
plug them into different AC power outlets/sockets.
■
Reposition the TV and/or radio antennas and cables until the interference stops. For external
antennas, call your local electrician.
■
Use coaxial cables with radio and television antennas.
Operating Precautions
Do not place any liquid containers such as vases or coffee cups on the printer. Liquids spilt
on the printer can cause a fire or electric shock.
Do not place any metal parts such as staples or clips on the printer. If metal or flammable
materials get into the printer, they can short circuit internal components and cause a fire or
electric shocks.
If debris (metal or liquid) gets into the printer, turn off and unplug the printer. After that, call
your dealer or Brother Customer Service immediately. Operating a debris-contaminated
printer can cause a fire or electric shocks.
Never open or remove printer covers that are secured with screws unless specifically
instructed to do so in the this guide. High-voltage components can cause electric shocks.
Do not try to alter the printer's structure or modify any parts. Unauthorized modifications can
cause fire.
This printer complies with the IEC60825 (Class 1) international laser standard. This means
that the printer does not present any risk of injury to individuals from laser radiation. Various
covers confine the laser radiation to the inside of the printer; hence, users cannot incur
injury from the laser under normal operating conditions. Removing covers, unless
instructed to do so in this guide, can cause injury from laser radiation.
