Understanding the printer operator panel
The operator panel on your printer is a 4-line backlit gray scale display that can show both graphics and text. The Back, 
Menu, and Stop buttons are located to the left of the display, the navigation buttons are located below the display, and the 
numeric pad is located to the right of the display.
Translations label
If English is not your native language, peel the backing off the translations label that shipped with your printer and affix it 
inside the front door as shown. The label serves as a guide for interpreting the operator panel buttons.

The use of the buttons and the layout of the display panel are described in the following table.
ButtonFunction
Back Press the Back button to return to the last screen you viewed.
Note:Changes made on a screen will not be applied if you press the Back button.
Menu Press the Menu button to open the menu index. 
Note:The printer must be in the Ready state to access the menu index. A message 
indicating the menus are unavailable will appear if the printer is not ready.
Stop Press the Stop button to stop the mechanical operation of the printer. After pressing Stop, 
the message Stopping is displayed. When the printer has stopped, the status line in the 
operator panel will show Stopped, and a list of options will appear.
The Up and Down buttons are used to move up and down lists.
When navigating through a list using the Up or Down button, the cursor 
moves one line at a time. Pressing the Down button at the bottom of the 
screen changes the screen to the next whole page.
The Left and Right buttons are used to move within a screen such as moving 
from one menu index item to another. They are also used to scroll through 
text that will not fit on the screen.
The Select button is used to initiate action on a selection. Press Select when 
the cursor appears next to the selection you want such as following a link, 
submitting a configuration item, or when you want to start or cancel a job.

The numeric pad consists of numbers, a pound # sign, and a backspace button. The 5 
button has a raised bump for non-visual orientation. 
The numbers are used to enter numeric values for items like quantities or PINs. The 
backspace is used to delete the number to the left of the cursor. Pressing the backspace 
multiple times will delete additional entries.
Note:The pound # sign is not used.
Display panel
The display panel shows messages and graphics describing the current state of the printer and indicating possible printer 
problems you must resolve.
The top line of the display is the header line. If applicable, it will contain the graphic indicating the Back button can be 
used. It will also display the current status, and the Supplies (Warnings) status. If multiple warnings are present, each 
warning will be separated by a comma.
The other three lines of the display are the body of the screen. This is where you view printer status, supplies messages, 
show-me screens, and make selections.
