Notes:
The printer has detected a non-Lexmark supply or part installed in the printer.
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. For more information, see Using genuine Lexmark parts and supplies.
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 associated components.
To accept any and all of these risks and to proceed with the use of non-genuine supplies or parts in your printer, press and hold
and the # button on the control panel simultaneously for 15 seconds.
For non-touch-screen printer models, press
