Calling for service

When you call for printer service, describe the problem you are experiencing, the message on the display, and the troubleshooting steps you have already taken to find a solution.

You need to know your printer model type and serial number. See the label behind the toner waste container door of the printer for this information. The toner waste container door is on the left side of the printer.

The serial number is also listed on the menu settings page. For more informations, see Printing a menu settings page.

For service in the U.S. or Canada, call 1-800-Lexmark (1-800-539-6275). For other countries/regions, visit the Lexmark Web site at www.lexmark.com

Note: When calling for service, call from the location of the printer.

Checking an unresponsive printer

If your printer is not responding, first make sure:

•The power cord is plugged into the printer and a properly grounded electrical outlet.

•The electrical outlet is not turned off by any switch or breaker.

•The printer is not plugged into any surge protectors, uninterrupted power supplies, or extension cords.

•Other electrical equipment plugged into the outlet is working.

•The printer is turned on.

•The printer cable is securely attached to the printer and the host computer, print server, option, or other network device.
