There are two types of Setup options:

After you enter the settings, you must save the changes. You are usually prompted to do so. If 
you select Yes, your settings overwrite previous settings. If you select No, your previous 
settings are retained. If necessary, the Fiery X3eTY2 restarts after you exit from the Setup 
menu.

You are given choices that appear as buttons on the MFP 
touch panel (for example, Yes or No, or a list of options from 
which to choose). The currently selected value is highlighted. 
Press the button for the desired option on the touch panel. 

If the list of settings occupies more than one screen, use the 
up and down arrow buttons to scroll, and then choose the 
setting. As you proceed through the remaining options, make 
your selections, and press the appropriate button to save the 
changes when you are prompted.

You must specify the information for your site (the printer 
name or IP address, for example). Use the touch panel 
window keyboard to enter information.
