problem. For additional troubleshooting information, see 

Never open or remove printer covers that are secured with screws unless specifically 

instructed to do so in the manual. A high voltage component can cause electric shock. Do not try to 
alter the printer configuration or modify any parts. An unauthorized modification can cause smoke 
or fire.

Probable causes of trouble are that the printer, computer, server or other hardware is not 

correctly set for the network environment you are using, or a printer restriction has been exceeded.
