While it is possible to change the MAC address of a network device, it is not common practice to do so. For this reason,
MAC addresses are considered permanent. IP addresses are easily changed, so MAC addresses are a more reliable
method of identifying a specific device on a network.
Routers with security capabilities may allow filtering of MAC addresses on networks. This allows a managed list of
devices to access the network, identified by their MAC addresses, as well as prevent access from unwanted devices. If
your network uses MAC address filtering, then be sure to add the MAC address of the printer to the list of allowed
devices.
How do I find the MAC address?
Network devices have a unique hardware identification number to distinguish them from other devices on the network.
This is called the MAC (Media Access Control) address. Other devices sometimes use a type of MAC address called
Universally Administered Address (UAA).
When installing the printer on a network, make sure you select the printer with the correct MAC address.
The MAC address of the internal print server is a series of letters and numbers.
Notes:
• A list of MAC addresses can be set on an access point (wireless router) so that only devices with matching MAC
addresses are allowed to operate on the network. This is called MAC filtering. If MAC filtering is enabled in your
access point and you want to add a printer to your network, then the MAC address of the printer must be
included in the MAC filter list.
