Setup Canon Pixma Printer Using WPS Connection

If the access point you are going to use contains a WPS push button, then you can make a wireless connection easily. Most WPS-enabled access points contain WPA or WPA2 security which makes it even better. Now, follow these steps to set up a wireless connection:

1. Turn on the printer and then press & hold the button with the wifi icon on it. Keep holding the button until an alarm flashes.
2. The light next to the button will start flashing, which is when you should press the WPS button of the access point you are using. Make sure that you press within 2 minutes.
3. The light on the printer will keep flashing until it is searching and will stop after making a connection.
