To verify communication over the network
1. Windows: Click Start, click Run, and then type cmd. An MS-DOS command prompt opens.
-or-
Mac: Click Applications, click Utilities, and then open the Terminal application. The terminal
window opens.
2. Type ping followed by the IP address. For example, type ping XXX.XXX.XXX.XXX where
"XXX.XXX.XXX.XXX" is the IP address that is shown on the HP Jetdirect configuration page. If the
MFP is communicating over the network, the response is a list of replies from the MFP.
3. Verify that the IP address is not a duplicate address on the network by using the address resolution
protocol (arp -a) command. At the prompt, type arp -a. Find the IP address in the list and compare
its physical address to the hardware address that is listed on the HP Jetdirect configuration page
in the section called HP Jetdirect Configuration. If the addresses match, all network
communications are valid.
4. If you cannot verify that the MFP is communicating over the network, contact the network
administrator.
