The wireless modules in these products use a MAC address that is not part of the Lexmark MAC address block.
Network monitoring tools that scan the MAC address of the wireless card may not identify the printer as a Lexmark device when connected wirelessly.
Connect the device via an Ethernet cable or allow the printer MAC address in the security tool.
