This section contains information about understanding the operator panel, changing printer
settings, and understanding operator panel menus.
You can change most printer settings from your software application or printer driver. Settings
you change from the application or printer driver apply only to the job you are preparing to
send to the printer.
Changes made to printer settings from a software application override changes made from
the printer operator panel.
If you cannot change a setting from your application, use the printer operator panel or the
remote operator panel available from MarkVision™. Changing a printer setting from the
printer operator panel or from MarkVision makes that setting the user default.

printer settings, and respond to printer messages.
The numbers 1 through 6 appear beside the operator panel buttons; these numbers are used

The diagram in Using printer menus shows the menu items in each menu.
An asterisk (*) next to a value indicates the factory default setting. Factory defaults may differ
for different countries.
Factory defaults are the function settings in effect the first time you turn your printer on. These
remain in effect until you change them. Factory defaults are restored if you select the Restore
value for the Factory Defaults menu item in the Utilities Menu. See Utilities Menu for more
information.
When you select a new setting from the operator panel, the asterisk moves next to the
selected setting to identify it as the current user default.
User defaults are the settings you select for different printer functions and store in printer
memory. Once stored, these settings remain active until new ones are stored or the factory
defaults are restored.
Note: Settings you choose from your software application may override the
settings you select from the operator panel.

Menus Disabled
If your printer is configured as a network printer available to a number of users, Menus
Disabled may appear when you press Menu from the Ready state. Disabling the menus
prevents users from using the operator panel to inadvertently change a printer default that
has been set by the person managing the printer. You can still use Print and Hold features,
clear messages, and select items from the Job Menu when printing a job, but you cannot
change other printer settings. You can, however, use your printer driver to override printer
defaults and select settings for individual print jobs.
