The environment necessary for the wireless connection

Before connecting this printer to the network, confirm the following two items, (A) and (B).

(A) Access point or router (supporting IEEE802.11b/g/n)

An access point or router is a relay device which connects not only the Internet and network devices such as a computer or printer, but also one network device to another.

So, your access point or router must be properly set before you go to the next setup step.

(B) The computer to be used with the printer must be connected to the network.

In order to confirm whether the computer to be used with the printer is connected to the network, try to browse the Internet website from the computer.


An "Ad-hoc connection," which establishes a direct connection to the computer over a wireless connection without an access point, is not supported. Be sure to prepare an access point.
