Doctor to help diagnose and get assistance in installing and using HPprinters on
home network. To use this tool, visit the HP Wireless Printing Center www.hp.com/
go/wirelessprinting.
Step 1 - Make sure the wireless (802.11) light is turned on
The Wireless light in the printer control panel indicates the status of the wireless
capabilities.
To turn on wireless, touch (right arrow), touch Setup, touch Network, touch
Wireless Radio, and then select Yes.
NOTE: If your printer supports Ethernet networking, make sure that an Ethernet
cable has not been connected to the printer. Connecting an Ethernet cable turns off
the printer's wireless capabilities.
Step 2 - 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 the printer. If you still are unable to connect, turn off the router, printer, and
your computer. Sometimes, turning off the power and then turning it back on recovers
from a network communication issue.
Step 3 - Run the Print Wireless Network Test
For wireless networking issues, run the Print Wireless Network Test. If a problem is
detected, the printed test report includes recommendations that might help solve the
problem.
TIP: If the Print Wireless Network Test indicates the signal is weak, try moving the
printer closer to the wireless router.
