Internal laser radiation

IMPORTANT - For Your Safety

To ensure safe operation, the supplied three-pin plug 
must be inserted only into a standard three-pin power 
outlet that is properly grounded through the normal 
household wiring. 
Extension cords used with this printer must be three-
pin plug type and correctly wired to provide proper 
grounding. Incorrectly wired extension cords may 
cause personal injury and equipment damage. 
The fact that the equipment operates satisfactorily 
does not imply that the power is grounded and that 
the installation is completely safe. For your safety, if 
in any doubt about the effective grounding of the 
power, call a qualified electrician. 
This product should be connected to an AC power 
source within the range indicated on the rating label. 
DO NOT connect it to a DC power source. If you are 
not sure, contact a qualified electrician.
