Installation Procedure
•Turn OFF the main power and unplug the power cord from the wall socket. If the
main power is not turned OFF before installing, an electric shock or malfunction
might occur.
•Do not put your hand into the controller box. It will result in a malfunction or injury.
•There is a possibility that the Device Server Option may malfunction due to static
electricity.
Only one of the following network interfaces can be installed at one time:
•File Format Converter
•IEEE 1284 Interface Board
•IEEE 802.11a/g/n Interface Unit
•Device Server Option
1. Remove the interface slot cover [A].
2. Insert the interface board [A] in the interface slot and then fasten it with screws.
When inserting into the slot, push the interface board until it is inserted properly.
3. Attach the ferrite cores to the Ethernet cable, while looping the cable at 3 cm (approx.

1.2 inch) [A] from the each end of the cable.
4. Only for installing this option in North America, bind both cores with cable ties [A] as
shown below.
5. Insert the Ethernet cable [A] into the Ethernet port on this option.
6. Insert the other end of the Ethernet cable to a PC for network setting.
When you install this option on the main machine for the first time, the interface board
must be connected directly to the PC to set up the IP address and other network
settings.
7. Plug the power cord and turn ON the power.

Location : [Device Management] > [Configuration] > [Network] > [Option
Network Interface]
1. Access the option’s IP address from a web browser.
2. Ping the option’s IP address from a command prompt on a Windows PC in
the same network as the mainframe.
If the IP address cannot be found (DHCP server), use the MAC address. This
is the number printed on the seal attached to the printed circuit board for the
USB server.
3. Use “RX” + the option’s MAC address and access a web browser.
Example: http://RX0080926A3264
4. Ping the “RX” + “MAC address” from the command prompt, on a windows
PC which is on the same network as the mainframe.

Notes for Energy Saving Mode Setting
If a machine with this option enters into the energy saving mode, printing is not possible
because of a communication error . Follow the instructions below to disable the machine’s
entering into the energy saving mode.
1. Enter SP mode, and then set SP5-191-001 (Power Setting: Power Str) to "0 (Off)".
IPAddress Setting
This section describes how to set an IP address on this option manually. Not only can you
set an IP address on the same network segment, but it is also possible to set an IP
address on a different network segment to share a single printer with devices in multiple
networks.
•The network setting of this option is initially assigned as follows:
IP address: 192.168.100.100 / Subnet mask: 255.255.255.0
•The network setting of the PC must be in the same network segment to
change the network setting of this option.
