CAUTION—SHOCK HAZARD: Remove the power cord from the electrical outlet before you connect or
disconnect any cable or electronic card or assembly for personal safety and to prevent damage to the
printer. Disconnect any connections between the printer and PCs/peripherals.
CAUTION—POTENTIAL INJURY: The printer weight is greater than 18 kg (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.
CAUTION—HOT SURFACE: The inside of the printer might be hot. To reduce the risk of injury from a hot

Performing the initial troubleshooting check

Before you start the troubleshooting procedures, perform the following checks:
•
Use genuine Lexmark supplies and parts for the best results. Third-party supplies or parts may affect the
performance, reliability, or life of the printer and its imaging components.
•
With the power cord unplugged from the electrical outlet, check that the cord is free from the breakage,
short circuits, disconnected wires, or incorrect connections.
•
Make sure the printer is properly grounded. Check the power cord ground terminal.
•
Make sure the power supply line voltage is within 10% of the rated line voltage.
•
Make sure the machine is securely installed on a level surface in a well‑ventilated area.
•
Make sure the room temperature is between 16 and 32°C (60 and 90°F) and that the relative humidity is
between 20 and 80%.
