Fixing Poor Physical Connection
- Step 1 – Verify that the product is attached to the correct network port using a cable of the correct length.
- Step 2 – Verify that cable connections are secure.
- Step 3 – Look at the network port connection on the back of the product, and verify that the amber activity light and the green link-status light are lit.
- Step 4 – If the problem continues, try a different cable or port on the hub.
Changing the Incorrect IP Address for the Product
- Step 1 – Open the printer properties and click the Ports tab. Verify that the current IP address for the product is selected. The product IP address is listed on the product configuration page.
- Step 2 – If you installed the product using the HP standard TCP/IP port, select the box labeled Always print to this printer, even if its IP address changes.
- Step 3 – If you installed the product using a Microsoft standard TCP/IP port, use the hostname instead of the IP address.
- Step 4 – If the IP address is correct, delete the product and then add it again.
- Step 5 – Create a new HP TCP/IP port with the correct address.
Computer is Unable to Communicate with the Product
- Step 1 – Test network communication by pinging the network. (1) Open a command-line prompt on your computer. For Windows, click Start, click Run, and then type cmd. (2) Type ping followed by the IP address for your product. For Mac OS X, open the Network Utility, and then supply the IP address in the correct field in the Ping pane. (3) If the window displays round-trip times, the nwla cetwork is working.
- Step 2 – If the ping command failed, verify that the network hubs are on, and then verify that the network settings, the product, and the computer are all configured for the same network.
