● If your printer is connected by network, check that all components used in the network (network interface
cards, hubs, routers, switches, cables) are capable of high-speed operation. Is there a lot of traic from
other devices on the network?
● Did you specify Extended drying time in the front panel? Try changing the drying time to Optimal.
Communication failures between computer and printer
Some symptoms are:
● The front-panel display does not show the Receiving message when you have sent an image to the printer.
● Your computer displays an error message when you are trying to print.
● 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 application, see Printing on page 59.
● Ensure that the printer works correctly when printing from other applications.
● Remember that very large prints may take some time to receive, process and print.
● If your printer is connected to your computer through any other intermediate devices, such as switch boxes,
buer boxes, cable adapters, cable converters, and so on, try using it when connected directly to your
computer.
● Try another interface cable.
● Ensure that the graphic language setting is correct, see Change the graphic language setting on page 22.
● If the printer is connected by network, check that your printer has a static IP address. If it is using DHCP, the
IP address may change every time it is turned on, in which case the driver may not be able to nd it.
Cannot access the Embedded Web Server
If you have not done so already, read Embedded Web Server on page 15.
From the front panel, tap , then Security > Embedded Web Server.
If you are using a proxy server, try bypassing the server and accessing the Web server directly:
● In 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.
● In Safari for macOS, go to Safari > Preferences > Advanced and click the Proxies: Change Settings button.
Add the printer's IP address or its domain name to the list of exceptions, for which the proxy server is not
used, in the Bypass proxy settings for these Hosts & Domains eld.
If you still cannot connect, turn the printer o and back on with the power key on the front panel.
Cannot connect to the Internet
If your printer has diiculty in connecting to the Internet, it may start the Connectivity Wizard automatically.
