Safety Precautions
Safety Precautions
CAUTION: Handling ESD-Sensitive Parts
Many electronic parts use parts that are known to be sensitive to electrostatic discharge (ESD). To
prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic boards:
• Keep the ESD-sensitive part in its original shipping cont ainer (a special “ESD bag”) until you are
ready to install the part into the machine.
• Make the least-possible mov eme nts wit h you r body to prevent an i ncrease o f st atic el ectrici ty from
clothing fibers, carpets, and furniture.
• Use an ESD wrist strap on your wrist if available. Connect the wrist band to the system ground
point. This discharges any static electricity in your body to the machine.
• Hold the ESD-sensitiv e part by its edge co nn ector cover ; do no t touc h its pins. I f you are r emovi ng
a pluggable modu le, use the correct tool.
• Do not place the ESD-sens itive pa rt on any met al surface; i f you nee d to pu t down t he ESD-se nsi-
tive part for any reason, first put it into its special bag.
• Metal surfaces are electrical grounds. They increas e the risk of damage because they make a di s-
charge path from your bo dy throug h th e ES D-sens itiv e par t. (La r g e met al objects can be disc harged
paths without being grounded.)
• Prevent ESD-sensiti ve parts from being accidentally touched by other personnel.
• Take ext ra care working with ESD-sensitiv e parts when cold weather hea ting is used becaus e low
humidity increases static electricity.
WARNING: To prevent the danger of electric shock, before installing any options be sure to
turn the power switch of the printer to the off [O] position and disconnect the power cord from
the wall outlet.
