Removal precautions

CAUTION—SHOCK HAZARD: For personal safety and to prevent damage to the printer, remove the 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.
CAUTION—POTENTIAL INJURY: The printer weight is greater than 18kg (40 lb) and requires two or more
trained personnel to lift it safely. Use the hand holds on the side of the printer. Make sure your fingers are not
under the printer when you lift or set the printer on the floor or another stable surface.
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, use the following instructions 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.
•
Put the ESD wrist strap on your wrist. 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 shroud (cover); do not touch its pins. If you are removing a
pluggable module, use the correct tool.
