If you encounter a problem with your printer, use the following table to troubleshoot and fix the

Warning: 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.
Caution: 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.
