Solving network connectivity problems
If the MFP is having problems communicating with the network, use the information in this section to
resolve the problem.
Troubleshooting network printing problems
NOTE HP recommends that you use the MFP CD-ROM to install and set up the MFP on a
network.
● Make sure that the network cable is securely seated into the MFP's RJ45 connector.
● Make sure that the Link LED on the formatter is lit. See Understanding lights on the formatter .
● Make sure that the I/O card is ready. Print a configuration page (see Configuration page ). If an
HP Jetdirect print server is installed, printing a configuration page also prints a second page that
shows the network settings and status.
NOTE The HP Jetdirect print server supports various network protocols (TCP/IP, IPX/
SPX, Novell Netware, AppleTalk, and DCL/LLC). Make sure that the correct protocols and
network parameters are set correctly.
On the HP Jetdirect configuration page, verify the following items for your protocol:
● Under HP Jetdirect Configuration, the status is "I/O Card Ready".
● Protocol status is "Ready".
● An IP address is listed.
● The configuration method (Config by:) is listed correctly. See the network administrator if you
are not sure which method is correct.
● Try printing the job from another computer.
● To verify that a MFP works with a computer, use a parallel cable to connect it directly to a computer.
You will have to reinstall the printing software. Print a document from a program that has printed
correctly in the past. If this works, a problem with the network might exist.
● Contact your network administrator for assistance.
Verifying communication over the network
If the HP Jetdirect configuration page shows an IP address for the MFP, use this procedure to verify
that the MFP is communicating with other devices on the network.
