Caution:
It's very important to protect the printer controller board and
any associated daughterboard or module from electrostatic damage
while performing any task involving the controller board.
If an antistatic wrist strap is provided in your printer option kit,
attach one end of it to your wrist and the other end to any convenient
electrical ground (for example, the bare metal chassis of equipment,
as on the back of a computer, that is plugged in but
turned off).
Never attach the wrist strap to any piece of equipment with an
electrical current present. Turn off all power switches first. Plastic,
rubber, wood, painted metal surfaces, and telephones are not
acceptable grounding points. The printer isn't an acceptable
grounding point because it must be unplugged before you perform
this task.
If you don't have an antistatic wrist strap, discharge your body's
static electric charge by touching a grounded surface before you
handle any printer boards or components and before removing the
controller board. Also avoid walking around after grounding yourself.
