OK

Pressing OK when the printer is in the Ready state takes it offline, and the LCD will show the control panel menu.
Pressing OK allows you to choose the displayed menu or option. After changing a setting, the LCD shows Accepted and then the printer returns to the previous menu level.
Note Note
The options you have chosen are shown with an asterisk at the end of the display. Since the asterisk shows what you have chosen, you can easily see the current settings as you look through the LCD.
