Scanner has stopped working correctly

If the scanner stops scanning, follow these steps. After each step, start a scan to see if
the scanner is working. If the problem persists, proceed with the next step.
1. A cable might be loose. Ensure that both the USB cable and power supply are properly

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

2. Ensure that the scanner is receiving power.

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

c. 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.

3. Unplug the power cable from the power source, wait 60 seconds, and then plug it

back in.

4. Restart your computer.
5. Use the Add/Remove tool (in Windows Vista, the Programs and Features tool) from

the Control Panel to uninstall the following applications:
•

HP Scanjet N7710 Document ISIS/TWAIN

•

HP Scanjet N7710 Utilities

6. Reinstall using the HP Scanning Software CD that came with your scanner. When

you insert the CD, an installation dialog box launches automatically.
