A red X appears on the USB connect prompt
Solution Normally, a green check appears indicating that the plug and play is
successful. A red X indicates that the plug and play failed.
Do the following:
1. Verify that the control panel faceplate is firmly attached, unplug the HP All-in-
One power cord, and then plug it in again.
2. Verify that the USB and power cables are plugged in.
3. Click Retry to retry the plug and play setup. If this does not work, continue to
the next step.
4. Verify that the USB cable is set up properly as follows:
– Unplug the USB cable and plug it in again.
– Do not attach the USB cable to a keyboard or non-powered hub.
– Verify that the USB cable is 3 meters or less in length.
– If you have several USB devices attached to your computer, you might
want to unplug the other devices during the installation.
5. Continue with the installation and restart the computer when prompted.
6. If you are using a Windows computer, open the HP Solution Center and
check for the essential icons (Scan Picture, Scan Document, and Send a
Fax). If the essential icons do not appear, remove the software and then
reinstall it. For more information, see Uninstall and reinstall the software.
I received a message that an unknown error has occurred
Solution Try to continue with the installation. If that doesn’t work, stop and
then restart the installation, and follow the directions on the screen. If an error
occurs, you might need to uninstall and then reinstall the software. Do not simply
delete the HP All-in-One program files from your computer. Make sure to remove
them properly using the uninstall utility provided when you installed the HP Image
Zone software.
