Check the printhead initialization
When printheads are installed or replaced, the printer automatically prints an alignment
page to align the printheads. This process takes about seven minutes. Until this process is
complete, only the automatic alignment page can be printed.
Check the printer software installation
If the printer is turned off when printing, an alert message should appear on your computer
screen; otherwise, the printer software might not be installed correctly. To resolve this,
uninstall the software completely, and then reinstall the printer software. See Uninstalling
the printer software.
Check cable connections
z Make sure both ends of the cable (USB, parallel, or network) are secure.
z If the printer is connected to a network, check the following:
• Check the Link light on the back of the printer. See Network connector lights.
• Make sure you are not using a phone cord to connect the printer.
• The network hub, switch, or router is on and working properly.
Check printer setup for network environment
Ensure the correct printer driver and printer driver port are being used. For more
information about network connections, see Configuring the printer (Windows),
Configuring the printer (Mac OS), or the documentation provided by your network
vendors.
Check any personal firewall software installed on the computer
The personal software firewall is a security program that protects a computer from
intrusion. However, the firewall might block communication between the computer and the
printer. If there is a problem communicating with the printer, try temporarily disabling the
firewall. If the problem persists, the firewall is not the source of the communication
problem. 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 re-enable the firewall. See Configure network
options.
Check wireless communication settings
z Make sure the computer's wireless card is set to the correct wireless profile.
A wireless profile is a set of network settings unique to a given network. A single wireless
card might have several wireless profiles (for example, one for a home network and one for
an office network).
Open the configuration utility for the network card installed on your computer and ensure
that the profile selected is the profile for the printer's network.
z Make sure the printer's network settings match those of your network.
1 Do one of the following to find the settings for your network:
• Infrastructure communication mode: Open the Wireless Access Point's (WAP)
configuration utility.
• Ad hoc communication mode: Open the configuration utility for the network card
installed in your computer.
