Troubleshooting

Solving option problems

If an option does not operate correctly after it is installed or if it quits working:

•Turn the printer off, wait for about 10 seconds, and turn the printer on. If this does not fix the problem, unplug the printer, and check the connection between the option and printer.

•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. For more informations, see Printing a menu settings page.

•Make sure the option is selected in the software application you are using.
