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 aect 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.
Power‑on Reset (POR) sequence
When you turn on the printer, it performs a POR sequence.
Check for correct POR functioning of the base printer by observing the following:
1 The control panel indicator light turns on.
2 The control panel display turns on.
3 A splash screen appears on the display.
4 The cooling fan turns on.
5 The fuser heater turns on.
Note: The fuser takes longer to warm up from a cold start than from a warm start.
6 The main drive motor turns on.
