13 LED INDICATIONS
The LED indicator at the front of the Ap1400 has a number of colour combinations, which repeat in up
to a 4-phase pattern to provide status information (see table below).
In summary, if the LED is constant green it indicates that the printer is operating normally. Flashing
on and off indicates that Spool mode is active and no printing can take place. Red warns of a low
power supply voltage or other problem. No light indicates that the unit is off.

Although this table may seem complicated, few applications will produce many of the combinations.
Other LED Patterns
Other LED patterns may be programmed into the Ap1400 on request or by the system designer.
Please refer to the Programmers’ Guide for details of how to configure these functions.
