Printer settings
Factory settings
The printer settings have been set at the factory before shipment. They are called factory settings.
Although you can operate the printer with these factory settings unchanged, you can tailor the printer
with user settings. See List of factory settings on page 3-24.
The changed user settings can be restored to the default factory settings with the RESET MENU menu.
See RESET MENU on page 3-21.
Changing the user settings does not affect the factory settings. You cannot modify the present
factory settings.
