Verify installation preliminaries

Make sure to use the installation CD that contains the correct HP software for your operating system.

Before installing HP software, make sure that all other programs are closed.

If the computer does not recognize the path to the CD-ROM drive that you type, make sure that you are specifying the correct drive letter.

If the computer cannot recognize the installation CD in the CD-ROM drive, inspect the installation CD for damage. You can download the printer driver from the HP Web site (www.hp.com/support).

NOTE: After correcting any problems, run the installation program again.

Solve network problems

General network troubleshooting

If you are unable to install the HP software, verify that:

ƕAll cable connections to the computer and the printer are secure.

ƕThe network is operational and the network hub is turned on.

ƕAll applications, including virus protection programs, spyware protection programs, and firewalls, are closed or disabled for computers running Windows.

ƕMake sure the printer is installed on the same subnet as the computers that use the printer.

ƕIf the installation program cannot discover the printer, print the network configuration page and enter the IP address manually in the installation program. For more information, see Understand the network configuration page.

If you are using a computer running Windows, make sure that the network ports created in the printer driver match the printer IP address:

ƕPrint the printer’s network configuration page.

ƕClick Start, then click Printers or Printers and Faxes. - Or -

Click Start, click Control Panel, and then double-click Printers.

ƕRight-click the printer icon, click Properties, and then click the Ports tab.

ƕSelect the TCP/IP port for the printer, and then click Configure Port.

ƕCompare the IP address listed in the dialog box and make sure it matches the IP address listed on the network configuration page. If the IP addresses are different, change the IP address in the dialog box to match the address on the network configuration page.

ƕClick OK twice to save the settings and close the dialog boxes.

Problems connecting to a wired network

If the Network light on the printer control panel does not turn on, make sure that all of the “General network troubleshooting” conditions are met.

Though it is not recommended that you assign the printer with a static IP address, you might resolve some installation problems (such as a conflict with a personal firewall) by doing so.
