again. Press the On button on the control panel to turn the HP Photosmart off, and press it
again to turn the device on. Also, turn off the power on your router or hub, and then turn it
on again.

ensure connections are secure.

Cause: Cables are not connected properly.
Solution: Check the following cables to ensure they are connected properly:
Cables between the HP Photosmart and the hub or router
Cables between the hub or router and your computer
Cables to and from your modem or HP Photosmart Internet connection (if applicable)
Cause: A firewall, anti-virus, or anti-spyware application is preventing the HP Photosmart from
accessing your computer.
Solution: Uninstall the HP Photosmart software, and then reboot your computer. Temporarily
disable anti-virus or anti-spyware applications, and then reinstall the HP Photosmart software.
You can re-enable your anti-virus or anti-spyware applications after installation is complete. If
you see firewall pop-up messages, you must always accept or allow the pop-up messages.
If the screen still appears, try uninstalling the HP Photosmart software, rebooting your computer,
and temporarily disabling your firewall before reinstalling the HP Photosmart software. You can
re-enable your firewall application after installation is complete. If you still see firewall pop-up
messages, you must always accept or allow the pop-up messages.
For more information, see the documentation provided with the firewall software.

computer.
Solution: Try temporarily disabling the VPN before proceeding with the installation.
