168 Functions of the Control Panel
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.
