Action

The power supply has an attached cable that plugs into the back of the scanner. The connector on the end of this cable has a green LED that is on when the power supply is functioning correctly.

The power supply also has an AC cable that is connected to the power supply on one end and plugged into a power outlet or surge protector on the other end.

1.Check that the green LED on the power supply cable connector is on.

2.If the green LED is not on, ensure that power is available to the power outlet or surge protector that the AC cable is plugged into.

3.If power is available to the power outlet or surge protector but the green LED is still not on, the power supply might be defective. Contact HP Support for assistance.

The USB cable is connected between the scanner and the computer.

●Use the cable that was included with the scanner. Another USB cable might not be compatible with the scanner.

●Ensure that the USB cable is securely connected between the scanner and the computer.
