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 on the printer for this information.
The serial number is also listed on the menu settings page. See Printing the menu settings page on page 64 for more
information.
For service in the U.S. or Canada, call 1-800-Lexmark (1-800-539-6275). See our Lexmark Web site at www.lexmark.com
for the numbers for other countries/regions.
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.
Once you have checked each of these possibilities, turn the printer off and back on. This often fixes the problem.
