Setting the IP Address

You can configure the machine to obtain an IP address automatically, without needing to specify any network settings to establish a network connection. Note that you may need to specify these settings, depending on your network type.

After configuring the IP address settings, make sure that the network settings are correctly specified.

Setting the IPv4 Address

By default, the IPv4 address is obtained automatically.

Follow the steps in the procedure below to change the IP address setting.

Before changing settings

Make sure the machine is turned ON and connected to a network.

• To use DHCP, BOOTP, or RARP

- One of the following can be used: DHCP, BOOTP, or RARP.

- When the machine is restarted, the IP address obtained using DHCP, BOOTP and RARP is displayed.

(The IP address obtained using DHCP, BOOTP, or RARP overwrites the current IP address.)

- It takes approximately two minutes to confirm that DHCP, BOOTP, or RARP can be used. We recommend that unused protocols be disabled.

• To use DHCP

You may not be able to print after turning the power OFF and ON to restart the machine. This is because a new IP address has been assigned.

When using DHCP, consult your network administrator and perform one of the following:

- Set the DNS dynamic update function

- Set the machine so that it uses the same IP address every time it starts up

• The IP address obtained using DHCP, BOOTP, or RARP

The IP address has higher priority when <Auto IP> is set to <On>.

1. Press [ ] (Menu).

2. Select <Network Settings> using [ ] or [ ], and then press [OK].

When the system manager ID and system manager PIN are specified, use the numeric keys to enter the ID and number, and then press [ ] (Log In/Out).

3. Select <TCP/IP Settings> using [ ] or [ ], and then press [OK].

4. Select <IPv4 Settings> using [ ] or [ ], and then press [OK].

5. Select <IP Address Settings> using [ ] or [ ], and then press [OK].

6. Select the method for setting the IP address using [ ] or [ ].

7. Change the IP address settings.

When <Auto Obtain> is selected

(1) Change <Auto Obtain> settings.

• <Select Protocol>

- <Off>: Do not obtain an IP address automatically.

- <DHCP>: Obtain an IP address automatically using DHCP. (The DHCP server needs to be running.)

- <BOOTP>: Obtain an IP address automatically using BOOTP. (The BOOTP daemon needs to be running.)

- <RARP>: Obtain an IP address automatically using RARP. (The RARP daemon needs to be running.)

• <Auto IP>

- <Off>: Do not obtain an IP address automatically.

- <On>: Obtain an IP address automatically.

(2) Select <Apply> using [ ] or [ ], and then press [OK].

When <Manual Obtain> is selected

This setting can be specified only when <Select Protocol> and <Auto IP> in <Auto Obtain> are set to <Off>.

(1) Enter the IP address.

After it has been entered, press [OK].

(2) Enter the subnet mask.

After it has been entered, press [OK].

(3) Enter the gateway address.

After it has been entered, press [OK].

8. Press [ ] (Menu) to close the menu screen.

9. Restart the machine.

Turn OFF the machine and wait for at least 10 seconds before turning it back ON.

Setting the IPv6 Address

Specify IPv6 settings using the Remote UI after you have specified the IPv4 settings.

• IPv6

- IPv4 must be specified to use IPv6.

- IPSec encryption (Security Architecture for Internet Protocol) is not supported.

• Addresses that cannot be entered in [IP Address] and [Default Router Address]

Addresses that start with "ff" (Multicast Address)

IPv6 address

The machine can store up to the following nine IPv6 addresses (One address can only be registered manually). In IPv6 communications, multiple IPv6 addresses can be used at the same time.

The stateless address is erased when the machine is restarted (when the power is turned ON).

1. Start the Remote UI and log on in system manager mode.

2. Click [Settings/Registration].

3. Click [Network Settings] -> [TCP/IP Settings].

4. Click [Edit] in [IPv6 Settings].

5. Select the [IPv6] check box.

6. Specify the stateless address.

Clear the [Stateless Address] check box when not using a stateless address.

7. Follow the steps in the procedure below to use a manual address.

Proceed to Step 8. when not using a manual address.

(1) Select the [Manual Address] check box.

(2) Enter [IP Address].

(3) Enter [Prefix Length].

(4) Enter [Default Router Address] if necessary.

8. Set DHCPv6.

Select the [Use DHCPv6] check box to use stateful DHCPv6.

9. Click [OK].

10. Restart the machine.

Turn OFF the machine and wait for at least 10 seconds before turning it back ON.

Checking IP Address Settings

• When the machine is not connected to the network properly

The IP address does not appear.

• When specifying a delay before establishing the network connection

The IP address, subnet mask, and gateway address appear after a specified length of time has elapsed. For details, "Specifying a Delay Before Establishing the Network Connection" in the e-Manual.

• When the machine is connected to a switching hub

The machine may not be able to connect to a network if your network settings are configured correctly. When this occurs, set a delay before establishing the network connection. For details, "Specifying a Delay Before Establishing the Network Connection" in the e-Manual.

Checking IPv4 address settings

1. Press [ ] (Status Monitor/Cancel).

2. Select <Network Information> using [ ] or [ ], and then press [OK].

3. Select <IPv4> using [ ] or [ ], and then press [OK].

4. Select the setting to check using [ ] or [ ], and then press [OK].

5. Check the information.

6. Press [ ] (Status Monitor/Cancel) to close the screen.

Checking IPv6 address settings

1. Press [ ] (Status Monitor/Cancel).

2. Select <Network Information> using [ ] or [ ], and then press [OK].

3. Select <IPv6> using [ ] or [ ], and then press [OK].

4. Select the setting to check using [ ] or [ ], and then press [OK].

5. Check the information.

6. Press [ ] (Status Monitor/Cancel) to close the screen.

Checking the Network Connection

Make sure that the network settings are correctly specified.

• When the network startup time is set

After the machine is turned ON, wait until the time specified in. <Startup Settings> has elapsed to execute a ping command. For details, see "Specifying a Delay Before Establishing the Network Connection" in the e-Manual.

• When the machine is connected to a switching hub

The machine may not be able to connect to a network if your network settings are configured correctly. When this occurs, set a longer startup time. For details, see "Specifying a Delay Before Establishing the Network Connection" in the e-Manual.

1. Press [ ] (Menu).

2. Select <Network Settings> using [ ] or [ ], and then press [OK].

When the system manager ID and system manager PIN are specified, use the numeric keys to enter the ID and number, and then press [ ] (Log In/Out).

3. Select <TCP/IP Settings> using [ ] or [ ], and then press [OK].

4. Select <IPv4 Settings> using [ ] or [ ], and then press [OK].

5. Select <PING Command> using [ ] or [ ], and then press [OK].

6. Enter an arbitrary IPv4 address existing on the network.

After it has been entered, press [OK].

7. Check the response.

• When the network connection is confirmed, <Received response from host.> is displayed.
• When the network connection is not confirmed, <No response from host.> is displayed. Recheck your network settings.

8. Press [ ] (Menu) to close the menu screen.
