 WARNING 
Installation 
 Do not set up the printer in a dusty environment. If 
dust collects inside the printer, it may cause fire or 
electric shocks or problems with correct operation. 
 
Be sure to connect the ground. If the ground 
connection is not secure, you run a high risk of 
receiving a serious electric shock, and problems with 
correct operation may also occur.   
Do not bend the cords excessively or fasten them 
too hard with staples or anything similar to secure 
cords, otherwise there is the danger that fire or 
electric shocks could occur. 
Printing 
 If a foreign object gets inside the printer, immediately 
turn off the power switch and disconnect the power 
cord, and arrange for a service call to resolve. 
If you continue to use the printer while there is a 
foreign object inside, it may result in fire or electric 
shocks or problems with correct operation. 
Do not allow the printer to come into contact with 
liquids, otherwise it may cause fire or electric shocks 
or problems with correct operation. 
If any liquid gets inside the printer, immediately turn 
off the power switch and disconnect the power cord. 
Contact Brother to arrange a service call to resolve.   
Do not use the printer when smoke or a bad odor 
coming from the printer, otherwise it may cause fire 
or electric shocks or problems with correct 
operation. 
Immediately turn off the power switch and 
disconnect the power cord, and arrange for a 
service call to resolve. 
 
 CAUTION 
Environmental requirements 
 
 
 
 
 
 
 
 
 
 
 Use the printer in an area which is free from 
sources of strong electrical  noise such as electrical 
line noise or static electric noise. 
Sources of strong electrical noise may cause 
problems with correct operation. 
Any fluctuations in the power supply voltage should 
be within ±10% of the rat ed voltage for the printer. 
Voltage fluctuations which are greater than this 
may cause problems with correct operation. 
The power supply capacity should be greater than 
the requirements for the printer’s power 
consumption. 
Insufficient power supply capacity may cause 
problems with correct operation. 
   
The ambient temperature should be within the 
range of 18
°C to 30
°C during use. 
Temperatures which are lower or higher than this 
may cause problems with correct operation. 
The relative humidity should be within the range of 
35% to 85% during use, and no dew formation 
should occur in any devices. 
Excessively dry or humid environments and dew 
formation may cause problems with correct 
operation. 
Use the printer in a place which is adequately 
ventilated. 
A slight odor is generated wh en the printed articles 
are being fixed by heat. 
In the event of an electr ical storm, turn off the 
power and disconnect the power cord from the wall 
outlet.
