11 Status Messages Through LEDs
LED "STATUS" (green) (6)
The STATUS LED will flash, when everything is in order. It will flash red in case of a failure. During fast charging,
the green STATUS LED will flash, while it permanently glows during trickle charge.
LED "IR Communication" (red) (7)
During data transmission, this LED will glow red under the IR window.
Status Messages of the Printer Through the Interfaces
Besides the optical status messages displayed by the three LEDs on the control panel of the printer, messages
are also transmitted through the serial interface. Most of the time, they are sent as single ASCII characters that
can be analyzed by the host.
