Troubleshooting

This section provides troubleshooting for common problems you may encounter while setting up and using the IB-53.

General

I cannot print to my printer/MFP over the network.

• Make sure that the IB-53 administrator password has been set. The administrator password can be set from the IB-53 built-in web page.

• Make sure that it is not running in recovery mode. Refer to Recovery Mode for more information on recovery modes.

• Make sure the computer and the IB-53 can communicate. Try using the ping command, ftp, etc.

• Verify the physical network connections. The network cables may be defective or not properly connected. Try changing the cables. Check the IB-53 and verify that the green link light is on and the red data light is flashing (receiving data).

• Turn the printer/MFP off, then on again. Try printing from another PC or to another network printer/MFP to help determine if the problem is with the PC or the printer/MFP.

I cannot see the IB-53 on the network, or often communication errors occur.

• Verify the physical installation of the IB-53. The network cables may not be properly connected. The network hub may be defective.

• Initialize the IB-53 firmware. See Resetting to Factory Defaults.

• If in a TCP/IP environment, try to directly connect the IB-53 and the PC on an isolated network. Connect only the IB-53 and the PC to a hub, or connect them directly using a crossover 10Base-T cable.

I cannot login to IB-53.

• Make sure that the ID/password entered on the login screen is correct.

• If you forget the password, initialize the IB-53 firmware. For instructions, see Firmware Initialization below.

• For security reasons, you will no longer be able to login after 3 incorrect login attempts. Please restart.

IP Address

How can I assign IP addresses properly?

• The Internet Protocol address is a unique number that represents a specific computer in a network. Format of the IP Address is four numbers separated by dots, e.g. '192.168.110.171.' Each number should be decimal of 0 through 255.

• The IP address is compiled from 'network ID + user ID.' This results in three different IP address 'classes.' Representing the network ID as 'n' and the user ID as 'u,' each class has the following attributes:

Class	IP Addressing	First Segment Range	Application	Number of Networks	Number of Users
A	n.u.u.u	0≤n≤127	Large scale network	126	16,777,214
B	n.n.u.u	128≤n≤191	Mid scale network	16,384	65,634
C	n.n.n.u	192≤n≤223	Small network	2,097,150	254

For example, in a class C network, you can assign an IP address as '192.168.40.1.'

• Devices having IP addresses with different network IDs ('n' above) cannot communicate even when they are in the same network segment.

Following is an example of a Class C IP network with 3 computers and 1 IB-53:

Computer A	192.168.40.1
Computer B	192.168.40.2
Computer C	192.168.40.10
IB-53 printer/MFP	192.168.40.20

DHCP/DHCPv6/BOOTP

The IP address changes unintentionally on my IB-53.

• If there are DHCP / DHCPv6 / BOOTP servers on a network, the IB-53 may obtain a different IP address every time it is powered on. To use a fixed IP address for a particular printer/MFP, access the IB-53's Web page and click Off-radio buttons at the DHCP / DHCPv6 / BOOTP settings.
  For more information on DHCP/BOOTP, see the IP Address Configuration.
  For more information on DHCPv6, see the IPv6 Address Configuration.

• To avoid unauthorized changes of the IB-53 settings, including from a browser, it is recommended that you define an administrator password. To change the password from a web browser:

1. Launch a web browser.

2. In the address bar, enter the IP address assigned to the IB-53.

3. The web browser displays the IB-53's Web page.

4. Login to the IB-53's Web page with administrator privileges.

   Refer to 1-3. Accessing IB-53's Web Page. When not logged in with administrator privileges, the settings cannot be changed.

5. From the left menu on the Web page, click General Settings > Password. The password configuration page is displayed.

6. Enter a new password.

7. Enter the same new password again to confirm it.

8. Click Submit.

Note and retain the password.

Resetting to Factory Defaults

How can I reset all IB-53 settings back to their factory default values?

The IB-53's firmware can be reset to the factory default setting by one of following 2 methods:

With a browser:

1. Access the IB-53 Web page.

2. From the left menu on the Web page, click General Settings > Reset > Reset.

With the push switch on the IB-53:

1. Press and hold the push switch for 2 seconds while turning on the printer/MFP.

2. Release the push switch when the Link Indicator (Green) on IB-53 lights.

3. The IB-53 will be initialized.

Printing a Status Page

How can I print a status page of the IB-53?

The status page of IB-53 can be printed by the method below:

1. Turn on the printer/MFP.

2. Press and hold the push switch for more than 5 seconds and then release it.

3. The status page will be printed.

Figure 2. Push Switch

It is also possible to print using the printer/MFP's operation panel. For details, refer to the operation manual of that printer/MFP.

Recovery Mode

When starting up in recovery mode, the version information is displayed as "1.0.0 R".
