Static electricity 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.

1.
Power down the printer. Do not unplug the printer; this preserves a
ground path to dissipate static charges. Disconnect the host interface
cables.
2.
Remove the printer’s upper half cover by first lifting the rear corners
of the cover and then the front corners.
