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 container (a special “ESD bag”) until you are
ready to install the part into the machine.
❥ Make the least-possible movements with your body to prevent an increase of static electricity
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-sensitive part by its edge connector cover; do not touch its pins. If you are remov-
ing a pluggable module, use the correct tool.
❥ Do not place the ESD-sensitive part on any metal surface; if you need to put down the ESD-sen-
sitive part for any reason, first put it into its special bag.
❥ Metal surfaces are electrical grounds. They increase the risk of damage because they make a
discharge path from your body through the ESD-sensitive part. (Large metal objects can be discharged paths without being grounded.)
❥ Prevent ESD-sensitive parts from being accidentally touched by other personnel.
❥ Take extra care working with ESD-sensitive parts when cold weather heating is used because
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.
