Cannot connect to my Scanner TS9120 - printing works fine

I'd also contact the mfr of this product. They will know and have all information regarding there product and how to set it up.

I have a Mac - OS/X 11.1 (Big Sur).

I have a Canon TS9120 printer/scanner.

Prior to migrating to my Orbi RBR850, I used an Airport router without issues.

Now, my printing is fine.

Now, my scanning doesn't work - no connection - can't find.

Same result from my TS9120 to the Mac, and from the Mac to the scanner.

Canon suggests to unblock these ports:

Port Purpose

TCP 80	For HTTP communication
TCP / UDP 161	For SNMP communication (MAXIFY Printers)
TCP / UDP 162	For SNMP communication (MAXIFY Printers)
TCP 443	For HTTPS communication such as cable-less setup operation (Applicable models only)
TCP / UDP 515	For printing using LPR protocol
TCP / UDP 9100	For printing using Raw protocol
TCP / UDP 1900	For Universal Plug and Play (UPnP) operation
TCP / UDP 5222	For Google Cloud Print and PIXMA Cloud Link
TCP / UDP 5357	For acquiring the printer information (WSDAPI)
TCP / UDP 8611	Canon BJNP port for printing
TCP / UDP 8612	Canon BJNP port for scanning (Applicable models only)

 

I can't tell if 8612 is open - not sure how to determine that. I'm assuing my connection issue is related to the Orbi as there was no issue with the previous router.  Being such a N00Bie to this, I'm not sure what to do next.
