A newly administered DHCP IP address has been configured on the printer. This can happen for any of the following reasons: - The printer or MFP network adapter has been reset.
- A network administrator failed to properly configure the DHCP server.
- A printer or network adapter has been replaced.
- The printer was disconnected from the network and moved to a different segment on the network.
- The printer was turned off for an extended period.
| Since the printer port is bound to the IP address, any IP address change on the printer can render the selected port invalid. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Identify the IP address under TCP/IP on the network settings page. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Verify Status - Connected on the network settings page. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Verify that Enable DHCP shows Active. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Click here for instructions on how to delete and reconfigure a port.

The host name used to create the original port has been changed. This can happen for any of the following reasons: - The printer or MFP network adapter has been reset.
- The host name has been changed.
- A printer or network adapter has been replaced.
| Because a port can be created using a host name, any change in host name on the printer can render the selected port invalid. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Identify the host name on the network settings page. HINT: This is the first part of the fully qualified domain name, e.g. station139.dhcp.hello.com ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Alternatively, access the Embedded Web Server and look under Reports > Print Server Setup Page > TCP/IP > Fully Qualified Domain Name. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) If you click Configure Port and see a different host name from that found on the network settings page, then you may have the wrong port selected. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Click here for instructions on how to delete and reconfigure a port.

Duplicate IP address causing network traffic collisions. Note: This occurs typically in larger business or enterprise environments. This can happen for any of the following reasons: - Before or after port configuration the IP address on the printer is manually configured.
- Manual IP address configuration on the printer disables DHCP, which can prevent proper IP address assignment.
- Manual IP address assignment causes the DHCP server to no longer see the printer.
- After the DHCP IP lease expires, the IP address reenters a pool of available DHCP IP addresses.
- Another network device on the network now obtains the same IP address.
- Two devices now share IP address, which prevents proper printer port communication.
| ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Identify the IP address under TCP/IP on the network settings page. Alternatively, use the Embedded Web Server path: Reports > Print Server Setup Page > TCP/IP > IP address. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Verify Status - Connected on the network settings page. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Turn off the printer. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Perform a ping test using the IP address. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) A duplicate IP address is present if the ping test is successful with the printer turned off. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Contact a network administrator to resolve this issue. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Click here for instructions on how to delete and reconfigure a port.

Print queue or queue-based print sharing condition. This can happen for any of the following reasons: - Problems with print and file sharing
- Host (print server) software firewall rules preventing communication with client workstation
- Necessary security permissions not assigned to allow queue-based printing
- A change in the share name, e.g. //computer name/printer name
- Network communication problem between print server and printer
| At the print server or the computer hosting the print share/queue: ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Verify that you can print. If not, see all other possibilities above. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Right-click on the printer object, and then click Sharing... ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Ensure that Do not share this printer is not selected. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Under Share this printer, take note of the printer share name. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) If you have a software firewall application, make sure you have included the remote client's IP address as a trusted zone or in the firewall's allow list. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Verify that share permissions are not preventing communication. Contact the network administrator or Microsoft for additional assistance. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) If using XP Professional, ensure that simple file sharing is enabled for Guests. Contact your network administrator or Microsoft for additional assistance. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Make sure the print server or computer hosting the print queue is turned on. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) See the following Topics since this computer performs the actual communication with the printer.
At the remote client or workstation: ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Right-click on the printer icon and select Properties from the drop-down menu. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Locate the port under the ports tab, e.g. //computer name/printer share name. ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Does the print server host computer name appear to be correct? ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Does the share name that was assigned on the print server appear correct? ![](https://publications.lexmark.com/media/ids_assets/images/transparent.png) Contact your network administrator or Microsoft for further assistance.
