LCD Reader

The LCD Reader is a software program that outputs the changing of the scanner front panel display to the computer monitor. The LCD Reader enables accessibility software tools to express what is being shown on the scanner front panel.

To use the LCD Reader, follow these steps:

1.On your hard drive, navigate to the C:\Program Files\Common Files\Hewlett-Packard \Scanjet\N8400 directory.

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

Control of the scanner buttons

To prevent buttons from being pushed accidentally, you can disable the buttons on the scanner front panel.

When the buttons are disabled, you always start scans and copies from the computer using scanning software. You can still press the Cancel button on the scanner front panel to stop a scan or copy and the Power Save button to put the scanner into Power Save mode.

To turn off the scanner buttons, follow these steps:

1.Open the HP Scanner Tools Utility.

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

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

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