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 you can try uninstalling and reinstalling the software.

Before you reinstall the software, check the troubleshooting checklist, and then do the following:

TURN THE WIRELESS ACCESS POINT OFF AND THEN BACK ON

Turning the access point off and then back on again can sometimes refresh network connections and resolve connectivity issues.

DISCONNECT FROM 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 try printing again.

MAKE SURE DEMO MODE IS TURNED OFF

Check to see if your printer has a Demo Mode. Selected printer features are not available when Demo Mode is turned on.

From the printer control panel, navigate to Demo Mode:

> Demo Mode.

Select Off, and then save the setting.

CHECK YOUR WEP KEY OR WPA PASSPHRASE

If your wireless access point is using Wired Equivalent Privacy (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 wireless access point is using Wi-Fi Protected Access (WPA) security, then the WPA passphrase should be:

•From 8 to 63 ASCII characters. ASCII characters in a WPA passphrase are case-sensitive. or

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

Note: If you do not know this information, then see the documentation that came with the wireless network, or contact the person who set up your wireless network.
