● Your computer or printer "hangs" (stays idle) while communication is taking place. ● Your printed output shows random or inexplicable errors (misplaced lines, partial graphics etc.) To solve a communication problem: ● Ensure that you have selected the correct printer in your software. ● Ensure that the printer works correctly when printing from other software. ● Remember that very large prints may take some time to receive, process and print. ● If the printer is connected to a network, try using it when connected directly to your computer through a FireWire or USB cable. See Connect the printer on page 191. ● If your printer is connected to your computer through any other intermediate devices, such as switch boxes, buffer boxes, cable adapters, cable converters, etc., try using it when connected directly to your computer. ● Try another interface cable. See Connect the printer on page 191. ● Ensure that the graphic language setting is correct. See Change the graphic language setting on page 65. I cannot access the Embedded Web Server from my browser If you have not done so already, please read Access the Embedded Web Server on page 17. ● Have you set an administrator password for the Embedded Web Server on the Security page, and then forgotten the password? If so, select the icon, then Printer configuration > Resets > Reset EWS password. ● At the printer's front panel, select the icon, then Printer configuration > Allow EWS > On. ● Check that you have a TCP/IP (network or FireWire) connection to your printer. If you connect directly to your printer with a USB cable, you cannot use the Embedded Web Server. ● If you are using a FireWire connection, make sure that your computer's operating system supports IP over IEEE-1394 (FireWire). For example, Windows XP and Windows 2003 Server support IP over FireWire, but Windows 2000 does not. Make sure that your operating system is configured to use IP over FireWire. ● At the printer's front panel, check that IP is enabled for the type of connection you are using. Select the icon, then I/O setup, then the type of connection you are using, then View information, and check that you see IP enabled. If not, you may need to use a different type of connection. ● If you normally access the Web through a proxy server, try bypassing the proxy server and accessing the Web server directly. You can do this by modifying your browser settings. For instance, if you are using Internet Explorer 6 for Windows, go to Tools > Internet Options > Connections > LAN Settings and check the 'Bypass proxy server for local addresses' box. Alternatively, for more precise control, click the Advanced button and add the printer's IP address to the list of Exceptions for which the proxy server is not used. ● Try switching off the printer (with the Power key on the front panel) and then switching it on again.
