Static precautions
■ Leave the printer plugged into its power outlet. This preserves a
ground path for static discharges.
■ Touch the printer's bare metal frame often to discharge static
electricity from your body.
■ Handle the circuit board(s) by their edges only.
■ Do not lay the board(s) on a metal surface.
■ Make the least possible movements to avoid generating static
electricity.
■ Avoid wearing nylon or polyester clothing; they generate static
electricity.
