Connection errors
Use this section to solve the following errors generated when your HP all-in-one fails to
connect to the HP Instant Share service.
No network connection. See documentation.
Solution
Wired network
Network cables are loose or disconnected.
Incomplete or incorrect network connections prevent devices from communicating
with each other and generate problems in your network.
●
Check cable connections from the HP all-in-one to your gateway, router, or
hub to ensure connections are secure. If these connections are secure, check
your remaining cables to ensure connections are secure. Make sure none of
the cables are crushed or damaged.
●
Check all of the following connections: power cords; cables between the
HP all-in-one and the hub or router; cables between the hub or router and your
computer; and (if applicable) cables to and from your modem or Internet
connection.
●
If the connections mentioned above are secure, connect the cable to the
HP all-in-one to a working part of the network to verify the cable is bad, or
swap out remaining cables (one at a time) until you replace the malfunctioning
cable.
Note
You can also launch the HP Director from the desktop on your
computer, and click Status. A dialog box appears on the computer
stating whether or not the HP all-in-one is connected.
Solution
Wireless Network
There is some sort of interference.
The HP all-in-one is out of range of the access point.
●
Verify that physical barriers and other forms of interference are limited.
Signals transmitted between your HP all-in-one and access point are affected
by interference from other wireless devices - including cordless phones,
microwave ovens, and neighboring wireless networks. Physical objects
between the computer and the HP all-in-one also affect transmitted signals. If
this is occurring, move your network components closer to the HP all-in-one.

Troubleshooting
information
To minimize interference from another wireless network, try changing
channels.
●
Move the HP all-in-one and the access point closer together. If the distance
between your access point and the HP all-in-one is significant, try reducing the
distance. (The range for 802.11b is approximately 100 feet, and less if there is
any interference.) If possible, provide a clear path between the access point
and HP all-in-one, and minimize sources of radio interference.
Solution
Your HP all-in-one was connected to a network at one time. It is now directly
connected to a computer using a USB cable. The HP Instant Share application is
reading the previous network settings.
➔ If you are trying to use HP Instant Share while using a USB cable, reset the
network settings on the HP all-in-one or access HP Instant Share from the
HP Image Zone software on your computer.
Note
For more information on resetting network settings, see the Network
Guide that came with your HP all-in-one.
