Ways to Determine Printer Firmware Code Levels
Option 1
Print the Menu Settings Page. Do this from the printer's operator panel:
| Step | Action |
| 1 | Press the Menu button on the Operator Panel. |
| 2 | Touch  next to Reports. |
| 3 | Print the Menu Settings Page. Note: The printer should read ‘Printing Menu Settings Page’ and the menu settings page(s) should print out. |
| 4 | Check the code level under Device Information section on the menu settings pages. |
Option 2
Access the printer's Embedded Web Server (EWS). Before you begin, a functional network installation (wired or wireless – not a local USB installation) is required for access to the web server of any Lexmark network printer.
| Step | Action |
| 1 | Determine the IP address of the print server within the printer/MFP. |
| 2 | Launch your preferred web browser application (e.g., Firefox, Safari, Internet Explorer). |
| 3 | In the address field after the http://, enter the printer's IP address (e.g., http://192.168.1.5 or http://169.254.1.42). |
| 4 | Click on Reports. |
| 5 | To check for the code level, click on Device Information. |
