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.

1Turn off the printer, and then disconnect the power cord and all interface cables (parallel, serial, and Ethernet) from the printer.

2Access the printer controller board.

Use the instructions in the “Removing the Printer and Controller Board Covers” section of this chapter.
