Can't connect printer

Canon Color imageCLASS MF634Cdw supports AirPrint, and which would be the usual means to connect.

You will usually need to perform setup in the printer, as well.

No vendor drivers are required for printing when AirPrint is used.

The scanner supports TWAIN, so that usually means no vendor scanner drivers there, too.

Canon has a firmware update from about a year ago that you will want to apply, as well as tools and drivers for the non-AirPrint access:

Hello!

How are you attempting to connect to printer? USB, Wi-Fi, or ethernet?

That can mean either the printer Wi-Fi networking is misconfigured (this must happen on the printer), or that the printer itself is malfunctioning.
