What safety precautions should I follow when maintaining the HP Deskjet 2300?

Always unplug the printer from the wall outlet before cleaning, and never install or use the printer near water or when you are wet. Place the printer on a stable surface in a safe location where no one can step on or trip over the power cord, and only use the power cord and power adapter provided by HP. There are no user-serviceable parts inside — always refer servicing to qualified service personnel. (Page 7)
