Sometimes, nothing will make the scanner cooperate. When this happens, this is what I would suggest doing.
Shut down the computer and then reboot it, but don’t open any programs.
To completely shut down the scanner, there is a toggle switch on the back right side of the scanner. Turn it off. Wait 10 seconds.
Turn the toggle switch back on and wait 10 more seconds.
Turn on the green button on the front of the machine and wait 10 more seconds.
Reopen BScan. If there is anything in there, delete it by clicking “New Session”. Reopen Ariel.
If the scanner bulbs are not quite a full, calibrate the scanner.
Hope this helps, Kim
