Testing the printer
When you print a configuration page, the printer checks its internal controller and I/O interface,
and then prints a test page. You can review the configuration page printout to verify proper
installation of such options as paper trays or printer languages. For more information, see
page 205.
Engine test
The engine test print can be used to verify that the print engine is functioning correctly. For more
information, see page 190.
