Control Panel Operation

The control panel is made up of three
elements: a liquid crystal display (LCD)
panel, indicator lights, and buttons. The
LCD panel and indicator lights tell you the
current status of the printer, and you can use
the control panel buttons to make printer
settings, check consumable products, and
print status sheets. However, settings made
in your application and in the printer driver
usually override settings made at the control
panel.
