Updating firmware Printers inspect all downloaded firmware packages for required attributes before adopting and executing the packages. The firmware is packaged in a proprietary format and encrypted with a symmetric encryption algorithm through an embedded key that is known only to Lexmark. However, the strongest security measure comes from requiring all firmware packages to include multiple digital 2048-bit RSA signatures from Lexmark. If these signatures are not valid, or if the message logs indicate a change in firmware after the signatures were applied, then the firmware is discarded. 1 From the Embedded Web Server, click Settings > Device > Update Firmware. 2 Do either of the following: • Browse to the firmware file, and then click Upload. • Click Check for updates > I agree, start update.
