A 'ping' is a low-level test for network connectivity. This article outlines two procedures for performing a ping test.
Print the network settings page to obtain the printer's IP address. See the User's Guide for instructions.
NOTE: If the network settings page shows Status: Not Connected, this procedure will not be effective. You should consider other Wi-Fi related items - defective cables, defective or disabled ethernet drops (ports), or firewall issues - that may be preventing TCP/IP traffic.
- Double-click on the hard drive icon ( ).
- Double-click on Applications.
- Double-click on Utilities.
- Double-click on Terminal.
- At the terminal prompt, type ping, and then the printer IP address.
- If successful, you should see a growing list of the successful pings.
- Click Control + C to break the operation. Click here for image.
NOTE: This test can also be performed to ping a router's IP or IP gateway address.
--- 169.254.1.22 ping statistics --- (ad hoc example)
47 packets transmitted, 26 packets received, 44% packet loss
round-trip min/avg/max/stddev = 2.147/2.891/12.736/2.55 ms (milliseconds)
Effects - Packet loss
This sample indicates some packet loss; however, packet loss does not always indicate a problem. Packet loss occurs for many reasons, including:
- Signal degradation over the network medium. For example, on a wireless network, multipath interference or distance may affect ping results.
- Channel interference or oversaturated network lines
- Corrupted packets rejected in transit
- Driver issue or network applications
- Normal routing routines
If you are witnessing 100% or extremely high packet loss, consider the following suggestions:
- Reposition the antennas if connected to a wireless network.
- Reposition the printer closer to the access point or AirPort.
- Consider the purchase of antenna boosters if supported by your wireless router (access point).
- Consider a different ethernet cable if the printer supports this connection type.
- Consider a different ethernet drop (port) on the router if one is available.
- Test for a possible hardware or software problem.
- Test for a problem with your Internet Service Provider (ISP).
- Ping your computer's IP gateway and compare results. NOTE: The computer's gateway is typically equivalent to the router IP address.
If you need additional assistance, please contact Lexmark Technical Support. NOTE: When calling for support, you will be asked for your printer model type and serial number.
Please call from near the computer and printer in case the technician ask you to perform a task involving one of these devices.
