Function
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 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 to
select an item, to submit a configuration item, or to start or cancel a job.
The host USB Direct interface on the operator panel is used to plug in a USB
flash memory device and print PDF and supported graphic files (.gif, .jpeg, .jpg,
.bmp, .png, .tiff, .tif, .pcx, and .dcx files).
Note: A USB port is located on the back of the printer to connect a host
computer.
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 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.
