power cord from the electrical outlet before you connect or disconnect any cable, electronic board, or
assembly. Disconnect any connections between the printer and the PCs/peripherals.
Handling ESD
‑
sensitive parts
Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent
damage to ESD-sensitive parts, do the following:
•
Turn off the printer before removing logic boards.
•
Keep the parts in their original packing material until you are ready to install them into the printer.
•
Make the least-possible movements with your body to prevent an increase of static electricity from clothing
fibers, carpets, and furniture.
•
Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This action
discharges any static electricity in your body to the printer.
•
Hold the parts by their edge connector shroud. Do not touch its pins. If you are removing a pluggable module,
then use the correct tool.
•
If possible, keep all parts in a grounded metal cabinet.
•
Do not place the parts on the printer cover or on a metal table. If you need to put down the parts, then put
them into their packing material.
•
Prevent parts from being accidentally touched by other personnel. Cover the printer when you are not
working on it.
•
Be careful while working with the parts when cold-weather heating is used. Low humidity increases static
electricity.
