SAFETY PRECAUTIONS 

To use the MFC safely 

Please keep these instructions for later reference and read them before attempting any maintenance. 

NOTE:

 If there are faxes in the MFC's memory, you need to print them or save them before you turn  

off the power and unplug the MFC. (For MFC-7420) 

WARNING

There are high voltage electrodes 
inside the MFC.  Before you clean 
the inside of the MFC, make sure 
you have unplugged the telephone 
line cord first and then the power 
cord from the AC power outlet. 

Do not handle the plug with wet 
hands. 
Doing this might cause an electrical 
shock. 

After you use the MFC, some 
internal parts are extremely HOT! 
To prevent injuries, be careful not to 
put your fingers in the areas shown 
in the illustration. 

The fuser unit is marked with a 
caution label. 
Please do not remove or damage the 
label. 

To prevent injuries, be careful not to 
put your hands on the edge of the 
MFC under the scanner cover. 

To prevent injuries, be careful not to 
put your fingers in the area shown in
the illustrations. 

Do not use a vacuum cleaner to clean up scattered toner.  Doing this might cause the toner dust to 
ignite inside the vacuum cleaner, potentially starting a fire.  Please carefully clean the toner dust with 
a dry, lint-free cloth and dispose of it according to local regulations.
