Possible problem: You are using advanced forms of encryption, such as dynamic
encryption, WPA, or WPA-PSK, the encryption methods must be entered through the
embedded Web server. For more information, see.
In dynamic encryption, each device has a different key and all keys change frequently.
Dynamic encryption is much harder for an intruder to circumvent, since the keys are likely to
change before the intruder can reverse engineer them.
Possible problem: Your SSID or WEP key might be incorrectly set. Complete the following
procedure to set the SSID or WEP key:
1. Print a configuration page. To print a configuration page, when the printer is in the
Ready state, press and hold the GO button until the Ready light starts blinking. For more
information,.
2. Make sure the network SSID and WEP key on the device and the wireless network
match.
3. If one or both are incorrect, enter either the URL or device IP address from the
configuration page into the Address field on your Web browser. The printer EWS Home
page appears.
4. Select the Networking tab.
5. Click the Wireless option.
6. Enter the correct values in the appropriate sections (Network Name (SSID) and
Encryption).
7. Click Apply.
Possible problem: Your network uses multiple WEP keys, and you have chosen the wrong
key for transmitting.
1. Print a configuration page. To print a configuration page, when the printer is in the
Ready state, press and hold the GO button until the Ready light starts blinking. For more
information, see.
2. Enter either the URL or device IP address from the configuration page into the Address
field on your Web browser. The EWS Home page appears, showing the printer device
information.
3. Click the Networking tab.
4. Click the Wireless option.
5. In the Encryption section, select the Static (WEP) option.
6. Under Static (WEP), enter the WEP keys used by your network. In static encryption, the
same key is used for all devices on the network and the key remains the same for long
periods of time.
7. Choose the key to be used to encrypt transmitted data. (The installer defaults to WEP
Key 1.)
8. Click Apply.
9. If the installation has terminated, restart the printer software CD-ROM.
Possible problem: You are using advanced authentication protocols that are not supported
by the installation software, such as LEAP, PEAP, EAP-MD5, EAP-TLS, or EAP-TTLS
1. Print a configuration page. To print a configuration page, when the printer is in the
Ready state, press and hold the GO button until the Ready light starts blinking. For more
information, see Configuration page.
2. Enter either the URL or device IP address from the configuration page into the Address
field on your Web browser. The EWS Home page appears, showing the printer device
information.
3. Click the Networking tab.
4. Click the Wireless option.
5. In the Communication Mode section, select Infrastructure.
6. Select a network name (SSID) from the list of detected networks, or enter the name of a
new wireless network.
7. Select WPA/PSK, enter a pass phrase (from 8 to 63 characters in length, including
spaces) that will be used by the software to generate a pre-shared key.
NOTE All devices on the network must use the same pass phrase.
8. Click Apply.

Possible problem: No signal is being received by the device because it is not in range of
the access point (infrastructure) or computer (ad-hoc).
Move the printer and the computer closer together. If the distance between your computer
and the printer is significant, try reducing the distance. If possible, provide a clear path
between the computer and print server, and minimize sources of radio interference.
Possible problem: The setup program tried to change the computer’s wireless configuration
so that it can communicate to the printer, but was unable to reprogram the settings on the
computer’s wireless access card.
1. Quit all applications.
2. If your computer is connected to the Internet, disable the connection to your computer by
removing the Ethernet cable that connects the modem (cable, DSL, or dial-up) to your
computer.
3. Click Setup. The Setup menu appears.
4. Select 6. The Network menu appears.
5. Select 2. The wireless radio setting options appear.
NOTE The default setting for the wireless radio is Off.
6. Use the up and down buttons to select On.
7. Select OK.
8. Open the configuration utility for your wireless network adapter.
9. Write down the existing wireless profile settings.
10. Create a new wireless profile with the following values:
Communication mode: Ad Hoc
Network name (SSID): hpsetup
Encryption: disabled
NOTE This is the default configuration for your printer’s internal networking component.
11. Activate the profile.
When the configuration change is complete, the computer is ready to communicate on
the printer’s network. (The computer is no longer part of its original network.)
NOTE Unless you change your computer settings, the computer will continue to communicate with
your existing wireless network. However, the wireless device that you need to configure is on
its own network (called hpsetup). To configure that device, you need to temporarily change
your computer to the printer’s network.
12. Print a configuration page and obtain the IP address of the printer. To print a
configuration page, when the printer is in the Ready state, press and hold the GO
button until the Ready light starts blinking. For more information, see Configuration page.
13. Open your Web browser on your computer.
14. Type either the URL or device IP address from the configuration page into the Address
field in your browser. The EWS Home page appears.
15. Select the Networking tab.
16. Click the Wireless option.
17. In the appropriate section, enter the profile values you recorded in step 9.
18. Click Apply.
19. Exit the EWS by closing your browser.
20. Open the configuration utility for your wireless network adapter.
21. Restore the previous wireless profile settings.
22. Unplug the network cable from the printer.
23. Wait 60 seconds and then print a configuration page. The Wireless light should be on.
24. Open your Web browser on your computer.
25. Enter either the URL or device IP address from the configuration page into the Address
field in your browser. If the EWS Home page appears, your printer is properly configured.
26. Exit the EWS by closing your browser.
27. Insert the printer software installation CD into your computer's CD-ROM drive.
28. Run the installation software again.
