1.On your hard drive, navigate to the C:\Program Files\Common Files\Hewlett-Packard\Scanjet\9120\ directory.

2.To start the program, double-click hpled.exe.

NOTE: The LED Reader is not able to display the LED indications when there is a USB connection error or the scanner is off.

To turn off the scanner buttons, follow these steps:

2.On the Buttons tab, select the Disable front panel buttons check box.

To turn on the scanner buttons, clear the Disable front panel buttons check box.

NOTE: You must have administrative privileges on the computer to change the setting of this check box.
