3 Grasp the metal frame of the controller board and slide it out of the printer.
Place the board next to the printer. (When you put on the grounding wrist
strap, you want to be able to reach the controller board easily.)
IMPORTANT Be sure to put on the grounding wrist strap before handling the
hard disk or any internal printer parts. The strap grounds you to the printer,
preventing any static discharge that might harm the controller board or
printer. Wearing the strap cannot harm you. If you can’t find the grounding
wrist strap that comes with the internal hard disk, you can purchase one from
a computer dealer.
4 Wrap the end of the grounding strap that does not have copper foil on it around your
wrist.
The strap’s light adhesive coating keeps it attached to your wrist, while
allowing for easy removal.
5 Remove the backing from the piece of copper foil at the other end of the strap.
6 Attach the copper-foil end of the strap to the metal surface on the inside of the printer by
pressing the adhesive backing against the metal.
