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.
