Lexmark PRO4000C manual Cannot print over wireless network, Locating the printer IP address

Troubleshooting 56

Locating the printer IP address

•You can locate the printer IP address by viewing the printer network setup page. See the User's Guide on the software installation CD for more information on printing a network setup page.

Cannot print over wireless network

If you encountered problems while installing, or if your printer does not appear in the printers folder or as a printer option when sending a print job, then try uninstalling and reinstalling the software.

Before you reinstall the software, check the troubleshooting checklist, and then try one or more of the following:

TURN THE ACCESS POINT (WIRELESS ROUTER) OFF AND THEN BACK ON

Wait one minute for the printer and computer to reestablish the connection. This can sometimes refresh network connections and resolve connectivity issues.

DISCONNECT FROM YOUR VPN SESSION

When you are connected to another network through a VPN connection, you will not be able to access the printer over your wireless network. End your VPN session, and then try printing again.

MAKE SURE DEMO MODE IS TURNED OFF

Select printer features are not available when Demo Mode is turned on.

From the printer control panel, navigate to:

> Setup > OK > Demo Mode > OK > Off > OK

CHECK YOUR WEP KEY OR WPA PASSPHRASE

If your access point is using WEP security, then the WEP key should be:

•Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9. or

•Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard. ASCII characters in a WEP key are case‑sensitive.

If your access point is using WPA or WPA2 security, then the WPA/WPA2 preshared key/passphrase should be:

•Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9. or

•From 8 to 63 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard. ASCII characters in a WPA passphrase are case‑sensitive.

Note: If you do not know this information, then see the documentation that came with the access point, or contact your system support person.

CHECK IF YOUR ACCESS POINT HAS AN ASSOCIATION/REGISTRATION BUTTON

Wireless broadband boxes in Europe, the Middle East, and Africa such as Livebox, AliceBox, N9UF Box, Freebox, or Club Internet may require you to press an association/registration button when adding the printer to your wireless network.

If you are using one of these boxes and need more information, then see the documentation that came with your box, or contact your internet service provider (ISP).

MOVE YOUR ACCESS POINT AWAY FROM OTHER ELECTRONIC DEVICES

There may be temporary interference from electronic devices such as microwave ovens or other appliances, cordless phones, baby monitors, and security system cameras. Make sure your access point is not positioned too closely to these devices.

MOVE THE COMPUTER, PRINTER, OR BOTH CLOSER TO THE ACCESS POINT

The range of your wireless network depends on many factors, including the abilities of your access point and network adapters. If you are having trouble printing, then try placing the computer and printer no more than 100 feet apart.

CHECK THE WIRELESS SIGNAL QUALITY

Print a network setup page and check the signal quality. If the signal quality is listed as good or excellent, then another factor is causing the problem.

CHECK YOUR ADVANCED SECURITY SETTINGS

•If you are using MAC (Media Access Control) address filtering to limit access to your wireless network, then you must add the printer MAC address to the list of addresses allowed to connect to the access point.

•If you set the access point to issue a limited number of IP addresses, then you must change this so that the printer can be added.

Note: If you do not know how to make these changes, then see the documentation that came with the access point, or contact the person who set up your wireless network.

MAKE SURE YOUR COMPUTER IS CONNECTED TO YOUR ACCESS POINT

•See if you have access to the Internet by opening your Web browser and accessing any site.

•If there are other computers or resources on your wireless network, then check to see if you can access them from your computer.

MAKE SURE THAT YOUR COMPUTER AND PRINTER ARE CONNECTED TO THE SAME WIRELESS

NETWORK

If the printer is not on the same wireless network as the computer, then you will not be able to print wirelessly. The SSID of the printer must match the SSID of the computer, if the computer is already connected to the wireless network.
