Lexmark C720

You can change your printer setting by using your application software, your Lexmark printer

driver, the printer operator panel, or the remote operator panel available from MarkVision.

Note: Printer settings selected from a software application or driver override

default settings selected from the operator panel.

If there is a printer feature you cannot control from the application or printer driver, use the

printer operator panel or the remote operator panel available from MarkVision. Changing a

printer setting from the operator panel or from MarkVision makes that setting the user default

for all subsequent jobs sent to the printer. In most cases, settings you change from the

application or driver apply only to the job you are preparing to send to the printer.

Menu.

rently idle.
