Have Pixma MG5420 not working

[walterfaino]

I have a Pixma MG5420 and just upgraded to Xfinity XF1 Gateway. Now my printer does not work. Xfinity has done a restart/refresh to no avail. Canon or Comcast problem or user error?

Greetings,

If you are using a wired or wireless network connection, I'd refer to it as User Action Required, not user error.

Re-establishing a Network Connection After A Router Change:

Windows

MAC

or, start over.  Delete the printer from your computer and perform set up again.  This will allow you to re-establish the printer's connection to your network and re-install it on your system again.  See section on initial setup:
