2.7. Handling Problems during Installation Process
KeyScan team invested time and efforts to setup a smooth installation process, in case you
experience any problem please consider the following comments, we believe that most problems
may be resolved by the user following carefully the instructions below.
Installation Stage 2
The KeyScan is connected to the PC with the KeyScan USB2 cable but the green LED on the rear
of the KeyScan connector panel is not blinking
Try the following operations:
- Make sure the original KeyScan USB2 cable is being used and connected to a USB2 port on
your PC.
- Detach and after 10-20 seconds reconnect the cable, no need to shutdown the PC, the LED
should start blinking (it may take 10-30 seconds).
- If still do not blink restart the PC.
- If still do not blink try another USB port, if possible check the same port with another USB
device to make sure the USB port on your PC is functional.
Installation Stage 3
In case the software media is damaged download the KeyScan software from the KeyScan WEB
site. It is recommended to check the KeyScan WEB for software updates.
Installation Stage 4
When power adapter is connected, a red light should be seen when looking inside the document
feeding slot, the red light should be ON for at least 30 seconds and turned off automatically
sometime later.
If no red light appears then disconnect and reconnect the power adapter, recheck again for the red
light. This light indicates that the scanner receives the 7v power from the power adapter and the
scanner optical unit is functioning.
If the red light is still off check power outlet to make sure you do have power on that outlet, you
should check it by connecting another instrument to the same outlet.
You should always use only the KeyScan original power adapter.
Installation Stage 5
When trying to calibrate or scan, an error message that the scanner is not recognized or does not
exist appears:
- Try to disconnect and connect the KS810 (both power and USB cables).
- If still not working try to restart the PC, after restart make sure the Green LED is blinking.
- If still not working Installation problem, try to reinstall the scanner software.
