Antistatic Protection
Attention
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 either 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.
