Caution
It's very important to protect the printer 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’s static electric charge 
each time after walking around and before touching the printer 
controller board again.
1
Turn off the printer, and then disconnect the power cord and 
all interface cables (parallel, serial, AppleTalk, and optional) 
and SCSI hard disk cables, if any, from the printer.
2
Access the printer controller board.
Use the instructions in the “Removing the Printer and Controller 
Board Covers” section of this chapter.
