Introduction Certain types of problems can indicate there is a network communication problem. These problems include the following issues: Poor physical connection Check the cable connections. 1. Verify that the printer is attached to the correct network port using a cable of the correct length. 2. Verify that cable connections are secure. 3. Look at the network port connection on the back of the printer, and verify that the amber activity light flashes indicating network traffic, and the green link-status light is continuously lit indicating a network link. 4. If the problem continues, try a different cable or port on the hub. The computer is using the incorrect IP address for the printer If the computer is using the incorrect IP address for the printer, try these solutions. 1. Open the printer properties and click the Ports tab. Verify that the current IP address for the printer is selected. The printer IP address is listed on the printer configuration page. 2. If you installed the printer using the HP standard TCP/IP port, select the check box next to Always print to this printer, even if its IP address changes. 3. If you installed the printer using a Microsoft standard TCP/IP port, use the hostname instead of the IP address. 4. If the IP address is correct, delete the printer and then add it again. The computer is unable to communicate with the printer Verify that the printer is communicating with the network and your computer. 1. Test network communication by pinging the network. a. Open a command-line prompt on your computer. ● For Windows, click Start, click Run, type cmd, and then press Enter. ● For macOS, go to Applications, then Utilities, and open Terminal. b. Type ping followed by the IP address for your printer. c. If the window displays round-trip times, the network is working. 2. If the ping command failed, verify that the network hubs are on, and then verify that the network settings, the printer, and the computer are all configured for the same network (also known as subnet).
