Lexmark International Inc N8050 Manuel D’Utilisation

Make sure the network is operating properly.

See the network documentation, or contact your network support person if you are not sure 
that your network is operating correctly.

Make sure the printer driver is installed on the computer from which you are sending the print 
job.

The printer driver must be installed on each computer that uses the network printer.

Make sure the correct printer port is selected. 

Restart the computer.

Uninstall and then reinstall the printer software.

If the printer still does not print, see the printer documentation for help.

Make sure there is not a problem with the printer itself.

Attach the printer directly to the computer with a USB cable, and perform a local printer 
installation. If you are able to print when the printer is directly attached, there may be a 
problem with the network. See the network documentation, or contact your network support 
person.
