Support article for Lexmark E260
This article outlines the steps to troubleshoot a 31.xx Missing or Defective Cartridge error.
IMPORTANT REMINDER!
Note: If this corrects the issue, you will need to contact the point of purchase for questions about, or replacement of, the cartridge.

Check whether the cartridge is installed in the printer. If so, re-install it and ensure that it is properly seated inside the printer. Should you have already tried this and the error appears intermittently, proceed to Step 2.

Check your printer’s Engine Code Level. Follow any of the applicable options to do so. Then proceed to Step 3.

If the Engine Code Level is not 201c(or the latest) for E260/E360/E46x printers and 101c(or the latest) for X46x printers, use the Authorization Key Code below to download the latest code from the Lexmark website.
| Printer Model/s | Authorization Key Code |
|---|---|
| For E260, E36x, E46x | ex6xengine |
| For X46x | x46xengine |

After downloading the latest code, update the firmware. Navigate to the Firmware section of this product page for different methods to update the firmware.

Verify whether the error has been cleared. If issue persists, contact Lexmark Technical Support. Prepare a copy of the printer's latest Menu Settings page and a picture of the print cartridge contacts. Click here to see its location. Be ready to fax or email it upon request.
