a wireless network when a network cable is connected.
• Verify that the printer and wireless router are turned on and have power. Also
make sure the wireless switch is turned on.
• Verify that the printer is within the range of the wireless network. For most
networks, the printer must be within 30 m (100 ft) of the wireless access
point (wireless router).
• Verify the print driver is installed on the computer.
• Verify that the computer and printer connect to the same wireless
network.

Verify the printer fax settings
• To use a voice-mail service from the phone company or service provider,
make sure that the printer Rings to Answer setting is set to be fewer rings
than the telephone answering machine.
• If multiple phone numbers are assigned to the same physical phone line and
the line is shared by multiple devices, make sure that the printer is set to the
correct distinctive ring setting. Use a setting in which the printer answers
faxes and ignores other ring types.
• Configuring the Fax Speed setting to Medium(V.17) or Slow(V.29) can also
improve your ability to send a fax.
