Cannot Print Over a Network
If you cannot print over a network, try these solutions:
• Make sure that your product is turned on.
• Make sure you install your product's network software as described in your product documentation.
• Print a network status sheet and verify that the network settings are correct. If the network status is
Disconnected
, check any cable connections and turn your product off and then on again.
• Print a network connection report and check the codes and messages on the report to help determine
the cause of the problem.
• If you are using TCP/IP, make sure the product's IP address is set correctly for your network. If your
network does not assign IP addresses using DHCP, set the IP address manually.
