The printer user interface supports various routine tasks such as replacing printing supplies (labels, receipt paper, transfer ribbon, or others). For example, you are notified of a media-out condition by the color and state of two indicators.
Each status indicator icon represent a functional area of printer operation (such as SUPPLIES or NETWORK).
Depending on the operational state of the printer, the printer's status indicator lights convey the printer's status and activities (data downloading, over-temperature cooling cycle, or other) using a variety of states:
off (not lit — does NOT require your attention)
lit up red, green, or amber (orange yellow)
blinking / flashing
fading (bright to off), or
lighting up steady in a variety of patterns
The color of these status indicators may be:
Red — indicates that your attention is needed or that the printer is not ready to print.
Green — indicates the printer is ready or functioning.
Amber (orange/yellow) — indicates a busy or active process (data downloading, over-temperature cooling cycle, etc.).
Control buttons—You will use these in various combinations to access internal utilities that calibrate the printer to your media and change printer settings that are modifiable.
