Learning about the printer
Indicator light A two-toned LED is used on the operator panel, one color being green and the other being
red. The lights indicate whether the printer power is on, the printer is busy, idle, processing a
job, or requires operator intervention.
Numeric pad 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 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.
