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

ASCII characters in a WEP key are case‑sensitive.
