Removing and Replacing the 

Controller Board

▲

: It's very important to protect the controller board from 

electrostatic damage while performing this task.

If an anti-static 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 anti-static 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 cover. Redischarge your body each time after 
walking around and before touching the controller board again. 
Handle the controller board carefully, and try to handle it by the edges 
only.
