Installing the USB device server
The USB device server is an interface board that adds an Ethernet port to the printer.
With this device installed, two Ethernet cables can be connected at the same time using the standard port on the printer and an additional port on the USB device server. You can assign different IP addresses to each port, so the printer can print jobs from different network segments.
Procedure for installing the USB device server
Check the contents of the package.
Turn the printer off and unplug the power cord.
Loosen the two screws and remove the slot cover.
