any piece of equipment with an electrical current present. Turn

faces, and telephones are not acceptable grounding points. The
printer isn't an acceptable grounding point either because it must be
unplugged before you remove you can access the printer's controller
board.
If you don't have an anti-static wrist strap, discharge your body's
static electric charge by touching a grounded surface before you han-
dle any printer boards or components and before removing the con-
troller board cover. Redischarge your body each time after walking
around and before touching the printer controller board again. Handle
the tray carefully, and try to handle it by the edges only.
Incidental and consequential damages caused by not discharging
electrostatic buildup can affect your printer warranty.
