Troubleshooting overview
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%.
•
Avoid sites generating ammonia gas, high temperature, high humidity (near water faucets, kettles,
humidifiers), cold spaces, near open flames, and dusty areas.
•
Avoid sites exposed to direct sunlight.
•
Make sure the paper is the recommended paper for this printer.
•
Make a trial print with paper from a newly opened package, and check the result.
