Using genuine Lexmark parts and supplies

Your Lexmark printer is designed to function best with genuine Lexmark supplies and parts. Use of third-party supplies or parts may affect the performance, reliability, or life of the printer and its imaging components. Use of third-party supplies or parts can affect warranty coverage. Damage caused by the use of third-party supplies or parts is not covered by the warranty. All life indicators are designed to function with Lexmark supplies and parts, and may deliver unpredictable results if third-party supplies or parts are used. Imaging component usage beyond the intended life may damage your Lexmark printer or its associated components.

Ordering a maintenance kit

To identify the supported fuser type, view the label on the fuser. Do either of the following:

Remove the toner cartridge and the imaging unit. The two-digit fuser type code (such as 00 or 01) can be seen on the front of the fuser.
Warning—Potential Damage: Do not expose the imaging unit to direct light for more than 10 minutes. Extended exposure to light may cause print quality problems.
Pull down the printer rear door. The two-digit fuser type code (such as 00 or 01) can be seen on the rear of the fuser.

Notes:

Using certain types of paper may require more frequent replacement of the maintenance kit.
The separator roller, fuser, pick roller assembly, and transfer roller are all included in the maintenance kit and can be individually ordered and replaced if necessary.
