Solution: Check to see if you have an active network connection.
To see if you have an active network connection
▲ Check the two Ethernet indicator lights on the top and bottom of the RJ-45
Ethernet jack on the back of the HP All-in-One. The lights indicate the following:
a. Top light: If this light is a solid green, the device is properly connected to the
network, and communications have been established. If the top light is off,
there is no network connection.
b. Bottom light: This yellow light flashes when data is being sent or received by
the device over the network.
To establish an active network connection
1. Check the cable connections from the HP All-in-One to your gateway, router, or
hub to ensure connections are secure.
2. If the connections are secure, turn off the power on the HP All-in-One, and then
turn it on again. Press the On button on the control panel to turn the HP All-in-
One 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.
Cause: You were able to connect the HP All-in-One to the network previously, but
now it will not connect.
Solution: Turn off the HP All-in-One, the computer, and the router. Wait 30
seconds. Turn on the router first, and then turn on the HP All-in-One and the computer.
Cause: The HP All-in-One and computer are not connected to the same network.
Solution: Try accessing the Embedded Web Server on the HP All-in-One. To find
the IP address, print a network configuration page.
