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 when
the cursor is next to the selection you want, such as following a link,
submitting 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 files.
Note: A USB port is located on the back of the printer to connect a PC or other peripheral.
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.
The display 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.
