The Authenticator status lights
Four LEDs on the Authenticator give status and feedback to the user during the document reader
operation. They are used to show the operator process and quality checking information and can
occur either as steady or flashing indications.
The following section explains the default status light indications. Your software controls how the
status lights can be used in different methods. However the operation of the D SCAN Authenticator is
always the same.
When the Authenticator is turned on the boot sequence starts. Each step of the boot process uses three
LEDs in different combination (1, 2, 3).
Note
Only two or no LED are on during the boot process indicates an LED error.
When the boot process is complete the yellow LED indicates the standby mode (4). The device is
turned on but either the USB cable is not connected or the device driver is not loaded.
The green LED illuminates when the device is successfully initialized by the software and the
Authenticator is ready to scan.
