Solve connectivity problems
Solve direct-connect problems
If you have connected the product directly to a computer, check the cable.
● Verify that the cable is connected to the computer and to the product.
● Verify that the cable is not longer than 2 m (6.5 ft). Replace the cable if necessary.
● Verify that the cable is working correctly by connecting it to another product. Replace the cable if
necessary.
Solve network problems
Check the following items to verify that the product is communicating with the network. Before beginning,
print a configuration page. See
Print information pages on page 148 .
Problem Solution
Poor physical connection Verify that the product is attached to the correct network port using a cable of the
correct length.
Verify that cable connections are secure.
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.
If the problem continues, try a different cable or port on the hub.
The computer is unable to communicate
with the product. Use the command prompt to ping the product from your computer. For example:
ping 192.168.45.39
Verify that the ping displays round-trip times, which indicates that it is working.
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.
Incorrect link and duplex settings Hewlett-Packard recommends leaving this setting in automatic mode (the default
setting). See
Link speed and duplex settings on page 77 .
Incorrect IP address for the product on
the computer Use the correct IP address. The IP address is listed on the configuration page.
If the IP address is correct, delete the product and then add it again.
New software programs have caused
compatibility problems. Verify that any new software programs are correctly installed and that they use the
correct printer driver.
Your computer or workstation is set up
incorrectly. Check the network drivers, printer drivers, and the network redirection.
Verify that the operating system is configured correctly.
The protocol is disabled, or other
network settings are incorrect. Review the configuration page to check the status of the protocol. Enable it if
necessary.
Reconfigure the network settings if necessary. See Connect to a network
on page 68 .
