Solving problems that occur during installation

This section contains solutions to problems that might occur while initially installing the
printer to a wireless network.

Computer is unable to discover a device

1. Verify that the following cables are connected properly:

Power cables

Cables between the printer and the hub or router

Cables between the hub or router and your computer

(If applicable) cables to and from your modem or Internet connection

2. Verify that you have an active network connection.

Look at the light on the network connector. If the light is on, the printer is connected
to a wired network. If the light is off, check the cable connections from the printer to
the gateway, router, or hub to ensure connections are secure.

If the connections are secure, recycle the power on the printer to initiate another
search for a wireless network.

Personal software firewall is blocking communication

The personal software firewall is a security program that protects a computer from intrusion.
However, the personal firewall might block communication between the computer and the
printer. If you cannot communicate with the printer, try disabling the personal firewall. If you
are still unable to communicate with the printer, then re-enable the firewall. If disabling the
firewall allows you to communicate with the printer, you might want to assign the printer a
static IP address and then re-enable the firewall. For information about firewalls that are
used in an HP environment, see

.

Device is unable to connect to the network after removing
cable (infrastructure only)

If the access point/gateway has MAC filtering enabled, enter the MAC address of the printer
into the access point. The printer should then be able to connect to the wireless network. For
more information, see

Wireless access point (WAP) filters MAC addresses

System Requirements Error: No TCP/IP error displays

Make sure your LAN card is installed properly and set up for TCP/IP (Windows only). For
