Wireless

By following the instructions on the printer control panel and installing the HP printer software, you should have 

successfully connected the printer to the wireless network.
Note: If you want to change the type of connection the printer is using (for example, from USB to wireless or vice 

versa), you must use the tools provided with the HP printer software.
Tip: With Wi-Fi Direct, you can print wirelessly from a computer, smartphone, tablet, or other wireless-capable 

devices without connecting to an existing wireless network.
For more information, see “Change the connection type” and “Use Wi-Fi Direct” in the Help file (see “Learn more” on 

page 1 of this guide for more information about the Help file).

Solve wireless problems

1.  Make sure the printer is not connected to the network through an Ethernet cable

Wireless does not work if the printer is connected to the network through an Ethernet cable. Disconnect the 

Ethernet cable from the printer.

2.  Make sure the wireless light is turned on

If the blue light on the printer control panel is not lit, wireless might be turned off. To turn on wireless, touch 

or swipe down the tab at the top of a screen to open the Dashboard, and then touch  (Wireless), touch   

(Settings). Touch Wireless Settings, and then touch Wireless to turn it on.
If the blue wireless light is blinking, it means the printer is not connected to a network. Use the Wireless Setup 

Wizard available from the printer control panel to make a wireless connection. Touch or swipe down the tab at 

the top of a screen to open the Dashboard, and then touch  (Wireless), touch   (Settings). Touch 

Wireless 

Settings, touch Wireless Setup Wizard, and then follow the onscreen instructions.

3.  Make sure the computer is connected to the wireless network

Make sure your computer is connected to your wireless network. If you cannot connect the computer to the 

network, contact the person who set up your network or the router manufacturer; there might be a hardware 

issue with the router or computer.

4.  Run the wireless test

To check that the wireless connection is working properly, print the wireless test report. 
a.  Make sure the printer is turned on and paper is loaded in the tray.
b.  Touch or swipe down the tab at the top of a screen to open the Dashboard, and then touch  (Wireless), 

touch   (Settings).

c.  Touch Print Reports.
d.  Touch Wireless Test Report.
If the test fails, review the report for information on how to fix the problem and run the test again.
If the wireless signal is weak, try moving the printer closer to the wireless router.

5.  Restart components of the wireless network

Turn off the router and the printer, and then turn them back on in this order: router first and then printer. 

Sometimes, turning off devices and then turning them back on helps resolve network communication issues. 

If you still cannot connect, turn off the router, the printer, and the computer, and then turn them back on in this 

order: router first, then printer, and then computer.
