Getting Started with TellerScan® 4120
LED status indicators
The standard sequence for the two top cover LEDs is:
1. When the scanner is powered on, the power LED will light up ‘red’. This indicates
initial power to the scanner.
2. If the firmware and drivers have been properly loaded, once the application
launches and acquires the scanner, the right LED will now turn ‘green’.
3. Once the TellerScan® 4120 is synchronized with the application, the document
LED is now used to detect the presence of documents in the entry pocket.
4. Note: Both ends of the USB cable must be plugged in for the red LED light to turn
green. If the LED does not turn green, check and reseat the end of the USB
cable going into the PC and into the scanner.
