Ensure the toner cartridge was installed correctly and is making proper contact. Gently shake the cartridge side-to-side to redistribute the toner. Clean the printer's laser scanner assembly according to your printer's manual.

Verify that you are using a genuine Lexmark cartridge compatible with your printer model. Re-insert the cartridge to ensure it is seated correctly. Check for any protective tabs or seals that may still be attached.

This can sometimes happen if the cartridge was not fully seated. Try re-inserting it. If the issue persists and you have confirmed it's a new cartridge, contact Lexmark support.

Power cycle the printer (turn it off, unplug it, wait 30 seconds, then plug it back in and turn it on). If the error persists, remove and re-insert the toner cartridge.
