Solving network problems

(some models only)

NOTE: After correcting any of the following, run the

installation program again.

General network troubleshooting

• If you are unable to install the device software,

verify that:
• All cable connections to the computer and the

device are secure.

• The network is operational and the network hub

is turned on.

• All applications, including virus protection

programs, spyware protection programs, and

firewalls, are closed or disabled for computers

running Windows.

• Make sure the device is installed on the same

subnet as the computers that will be using the

device.

• If the installation program cannot discover the

device, print the Network configuration page

(see “To print the Network configuration page”

on page 28), and enter the IP address manually

in the installation program.

• If you are using a computer running Windows,

make sure that the network ports created in the

device driver match the device IP address:

1) Print the device’s Network configuration page.

2) From the Windows desktop, click Start,

point to Settings, and then click Printers or

Printers and Faxes.

Or

Click Start, click Control Panel, and then double-

click Printers.

3) Right-click the device icon, click Properties,

and then click the Ports tab.

Or

Right-click the device icon, click Run as

administrator, click Properties, click Continue,

and then click the Ports tab.

4) Select the TCP/IP port for the device, and then

click Configure Port.

5) Compare 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.

6) Click OK twice to save the settings and close

the dialog boxes.

Problems connecting to a

wired network

• If the Link light on the network connector does not

turn on, make sure that all of the “General network

troubleshooting” conditions listed above are met.

• Though it is not recommended that you assign the

device with a static IP address, you might resolve

some installation problems (such as a conflict with a

personal firewall) by doing so. For more information,

see the onscreen user guide on the Starter CD.

Solving wireless problems

(some models only)

If the device is unable to communicate with the network

after completing the wireless setup and software

installation, perform one or more of the following tasks.

Check the wireless

communication settings

• Make sure the computer’s wireless card is set to the

correct wireless profile. A wireless profile is a set of

network settings unique to a given network. A single

wireless card might have several wireless profiles

(for example, one for a home network and one for

an office network). Open the Configuration utility for

the network card installed on your computer, and

ensure that the profile selected is the profile for the

device’s network.

• Make sure the device’s network settings match those

of your network. Do one of the following to find the

settings for your network:
• Infrastructure communication: Open the wireless

access point’s (WAP) Configuration utility.

• Ad hoc communication: Open the Configuration

utility for the network card installed in your

computer.

• Compare the network’s settings to those on the

device’s Network configuration page (see “To print

the Network configuration page” on page 28), and

note any differences. Possible problems include the

following:

Troubleshooting

24

• The WAP filters hardware addresses

(MAC addresses). See “Add hardware addresses

to a wireless access point (WAP)” on page 24.

• One of these settings in the device might be

incorrect: communication mode, network name

(SSID), channel (ad hoc networks only),

authentication type, encryption.

See “Understanding 802.11 wireless network

settings” on page 19.

• Print a document. If the document still does not

print, then reset the device’s network settings

(see “Reset network configuration settings” on

page 24) and reinstall the device software.

If the wireless network settings are correct, the computer

might be associated with another wireless network.

Ensure that the computer is associated with the same

wireless network as that of the device.

Users can ensure this by checking the wireless settings

on their respective computers. In addition, ensure that

the computers have access to the wireless network.

If the wireless network settings are incorrect, follow these

steps to correct the device’s settings:

1. Connect the device to your network with a network

cable or to the computer using the network cable.

2. Open the device’s embedded Web server.
3. Click the Networking tab, and then click Wireless

(802.11) in the left pane.

4. Use the Wireless Setup wizard on the Wireless Setup

tab to change the device’s settings to match the

settings of the network.

5. Close the device’s embedded Web server, and then

disconnect the network cable from the device.

6. Uninstall the device software completely, and then

reinstall the software.

Add hardware addresses to

a wireless access point (WAP)

MAC filtering is a security feature in which a wireless

access point (WAP) is configured with a list of MAC

addresses (also called “hardware addresses”) of devices

that are allowed to gain access to the network through

the WAP. If the WAP does not have the hardware

address of a device attempting to access the network,

the WAP denies the device access to the network. If the

WAP filters MAC addresses, then the device’s MAC

address must be added to the WAP’s list of accepted

MAC addresses.

1. Print the Network configuration page. See “To print

the Network configuration page” on page 28.

2. Open the WAP’s configuration utility, and add the

device’s hardware address to the list of accepted

MAC addresses.

Reset network configuration

settings

If the device is still unable to communicate with the

network, reset the device’s network settings.

1. Press Setup. Press an arrow button to move to

Network, and then press OK.

2. Press an arrow button to move to Restore Network

Defaults, and then press OK.

3. Print the Network configuration page and verify that

the network settings have been reset. See “To print

the Network configuration page” on page 28.
By default, the network name (SSID) is “hpsetup”

and the communication mode is “ad hoc”.
