If the scanner takes a very long time after clicking on scan, this may be due to the following reasons:

The scanner remains connected to the power supply at all times.
Solution: disconnect the scanner from the power supply overnight and only switch it on after the computer has started up

The USB cable is too long.
Solution: From 1.50 m, an active USB extension should be used.

Problems with the USB port or with the USB controller.
Solution: Try a different USB port.

The wrong power supply unit is being used.
Solution: The scanner can only generate the required luminosity with the power supply unit supplied.

The wrong driver is being used.
Solution: Install the latest manufacturer drivers or try the Wia driver.

If no solution fits, please try the scanner on another computer.

If this still does not work, please contact our support by telephone.
