When the printer is not used over an extended period of time, switch it off and 
unplug it. When an unused printer is left connected to a power source for a long 
period, degraded insulation can cause electric shocks, current to leak, or fire. 

 

 

 

Switch off the printer before connecting the interface cable or options. Connecting 
the interface cable or options to a live printer can cause electric shocks.

Radio interference 
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 TV and/or radio. 

• 

Reposition the printer, TV and/or radio. 

• 

If the printer, TV and/or radio are plugged to the same socket, unplug them, then 
plug them into different sockets. 

• 

Reposition the TV and/or radio antennas and cables until the interference stops. For 
external antennas, consult your local electrician. 

• 

Use coaxial cables with radio and television antennas. 

 
 

 Operating Precautions 

 

WARNING

 

 

 

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, contact your dealer or authorized Brother service representative 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.
