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 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.
