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 standard electrical 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.

Disconnect device

You must install this printer near a power outlet that is easily accessible. In case of an emergency, you must 
disconnect the AC power cord from the AC power outlet to shut off the power completely.

Caution for LAN connection (For model HL-5250DN)

Connect this product to a LAN connection that is not subjected to overvoltages.
