Troubleshooting overview

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.

Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue offering

as much functionality as possible despite known issues. See

Warning—Potential Damage: Safe Mode is intended as a short‑term workaround and should be used only in

the case of a non‑critical error when a print job must be completed before service can be arranged to repair

the printer. The printer must be returned to standard operating mode before diagnostics can be run or

full‑function printing can continue.

You can enter Safe Mode in one of the following ways:

Enter Safe Mode from the Conﬁguration menu, and then POR the printer. See

For 2.4" display models, press the Stop and Back keys, and then POR the printer.
