Solving option problems
If an option does not operate correctly after it is installed, or if it quits working:
Turn the MFP off, wait for about 10 seconds, and turn the MFP on. If this does not fix the problem, unplug the MFP, 
and check the connection between the option and MFP.
Print the menu settings page, and check to see if the option is listed in the Installed Options list. If the option is not 
listed, reinstall it. See Printing the menu settings page for more information.
Make sure the option is selected in the software application you are using.
The following table lists MFP options and suggested corrective actions for related problems. If the suggested corrective 
action does not fix the problem, call your service representative.
