Lexmark MS331

Network Monitoring Software not identifying a wirelessly connected device as a Lexmark device

Affected Products:

Single-Function: B2236, B3340, B3442, C3224, C3426, CS331, CS431, MS431

Multifunction: CX331, CX431, MB2236, MB3442, MC3224, MC3426, MX431

Issue Description:

The wireless modules in these products use a MAC address that is not part of the Lexmark MAC address block.

If the device is connected to your network via wireless, network monitoring tools that are looking at the MAC address of the wireless card may not report this as a Lexmark device.


Connect the device via an ethernet cable or allow the printer's MAC address in the security tool.
