Chapter5 Troubleshooting 326 Error number Solution E-6 • Make sure that MAC address filtering is disabled. If enabled, please register the MAC address of the printer to prevent it from being filtered. For details, please refer to the manual of the access point. You can check the MAC address of the printer in the network settings column on the connection check report. • If Shared authentication is enabled in the access point's WEP security method, make sure that the authentication key and index are correct. E-8 • When the TCP/IP setting of the printer is set to automatic, enable DHCP on the access point.
• When the TCP/IP setting of the printer is set to manual, the manually set IP address is invalid because it is outside the valid range (such as 0.0.0.0). Set a valid IP address using the operation panel of the printer or using Web Config. E-9 Check the followings. • Is the device that uses the printer turned on? • From the device that uses the printer, is it possible to access the Internet and connect to other com- puter or network devices on the same network? If there are no problems, please use the installer to reconfigure your network settings. The installer can be obtained from the following website. https://epson.sn E-10 Check the followings.
• Are the other devices on the network turned on? • If you have set the printer’s TCP/IP settings manually, is the network address (IP address, subnet mask, and default gateway) correct? If the network address is incorrect, correct it. You can check the IP address, subnet mask, and default gateway in the network settings column on the connection check report. If you have enabled DHCP, set the IP address to Auto in the printer’s TCP/IP settings. If you want to set the IP address manually, check the printer’s IP address in the network settings column on the connection check report, then set the address in the printer’s network settings screen. Set the subnet mask to “255.255.255.0”.
E-11 Check the followings. • If you have set the printer’s TCP/IP settings manually, is the default gateway address correct? • Is the device specified as the default gateway turned on? Set the correct default gateway address. You can check the default gateway address in the network settings column on the connection check report. E-12 Check the followings. • Are the other devices on the network turned on? • Is the network address (IP address, subnet mask, default gateway) of the printer that you set manu- ally correct? • Are the network addresses (subnet mask and default gateway) of other devices the same? • Is the IP address of the printer duplicated with other devices?
If there are no problems, try the following. • On a computer on the same network as the printer, use the installer to reconfigure the network set- tings. The installer can be obtained from the following website. https://epson.sn • The security type "WEP" allows multiple security keys to be registered to the access point. When multiple keys are registered, make sure that the security key for the first (primary) index is set to the printer.
